Unformatted text preview: Page - 1 - of 5 CHE 361 Chemical Process Dynamics and Simulation 3 credits: T/R Lec/Rec, each 2 h/wk, Kearney 212 Winter Term 2012 Instructor: Dr. Keith L. Levien 203 Gleeson Hall [email protected] Office Hrs.: Mon, Wed, Thur 3-4pm and by email appointment TA: Xiangming Wu Office Hrs.: Tues 1-2, Wed 2-3pm Off Hrs in south end student lounge [email protected] Prerequisites: CHE 102 (knowledge of MATLAB), MTH 256 (ordinary differential eqns) CHE 331 (also CHE 211, 212, 311), personal laptop with latest version of MATAB 2011b running: Email: Every student must have ENGR and ONID accounts. Read email daily. Note: a class email distribution list will be generated from ENGR accounts. You could “forward” ENGR or ONID to any other account, but your provider (hotmail, gmail, etc.) may block emails from OSU and you would miss important information !! Student Learning Outcomes: By the end of the course, you will be able to: 1. use Laplace transforms to solve initial value problems (IVPs) for linear models of chemical processes or numerical methods to solve IVPs from linear or nonlinear models. 2. solve dynamic models of linear processes using the transfer function approach and apply this approach to approximate nonlinear chemical process behavior. 3. characterize classical first-order, second-order and first-over-second-order dynamics with standard parameters of gain, time constant, damping factor and numerator/zero time constant. This includes identifying values of poles and zero. 4. derive an appropriate linear dynamic model of a chemical process from first principles (mathematical derivation), including the conversion of physical variable ranges of input and output signals in order to analyze the dynamics of transmitters and final control elements as well as the physical process. 5. identify an appropriate linear dynamic model of a chemical process using parameter estimation techniques with step response data (a "bump" test) or from frequency domain data (Bode plot) obtained from an experiment or calculated using a computer-based model of a process. 6. analyze transfer function block diagrams which include series, parallel and loop configurations to find the "overall" transfer function between a single input and a single output. Page - 2 - of 5 Course Content and “Tentative” Schedule : This course includes fundamental principles of process dynamics and instrumentation used in the control of process variables such as pressure, temperature and flow rate.

HW7 due Thur Feb. 23 Page - 3 - of 5 Textbook: Required = Seborg, Edgar, Mellichamp and Doyle, Process Dynamics and Control, 3nd Edition, J. Wiley & Sons, 2011. Chaps: 1, 2-7, 13, 9 Appendix C = “SEMD3” Warning = the “International Edition” does not contain all chapters !!! Evaluation of Student Performance: The grades will be based upon examination of course work. An approximate breakdown is as follows: Homework 30% Midterms (2 x 15%) 30% Project 15% Final Exam 25% Homework Homework is instrumental in helping you grasp fundamental concepts and in exposing you to techniques and skills for applying these principles to real-life situations. Homework should be done in several sittings; you cannot expect to be successful doing homework quickly the night before it is due. You may discuss homework problems with your classmates (NOT COPY THEIR SOLUTIONS), but please try them on your own first. Additionally solutions must be written up independently. It is particularly important to document your independent work using computer programs, since this can be an area of abuse. For example, you must include your name, the class number, an assignment identifier and the date you created final MATLAB programs to be handed in for grading. Use the following guidelines for homework preparation (1st page = Cover Sheet): • • • • • • • Use clean, 8.5 x 11 inch paper. Engineering paper is preferred; neatness is important and appreciated. A copy of the cover sheet for each homework must be the attached to the front of your work. Copies of these cover pages will be available from the class web page. Write on only one side of the paper, and start a new problem on a new sheet of paper. Write the following in the upper right corner of each page: Your Name, CHE 361 HW number / due date Page number/Total pages, e.g. 3/7 = third page of 7 total. Securely staple all pages; do not fold or paper clip together. Show all of your work. Draw a block around your final answer(s). For graphical solutions, use MATLAB generated plots. Label the axes of your graph and include units using MATLAB, not added by hand writing. Provide MATLAB program and function listings (.m file printed out) on a separate sheet. Page - 4 - of 5 Midterm Exams Exams are scheduled as shown in the syllabus and last 110 minutes. The exams are open textbook (SEM2 text) and notes. It is your responsibility to bring a textbook, a calculator, pencils and paper. If you MUST miss one of these exams for an emergency situation, please let me know as soon as possible. If you oversleep or skip an exam you will not have an opportunity to make it up. If you have a valid (according to me) time conflict and you let me know in advance, there is the possibility of taking an exam at an alternate time. If you MUST miss a midterm or the Final Exam for an emergency situation, please let me know as soon as possible. If you oversleep or skip an exam you will not have an opportunity to make it up. If you have a valid (according to me) time conflict and you let me know in advance, there is the possibility of taking an exam at an alternate time. Class Attendance Attendance is MANDATORY! You are expected to attend every class and participate in discussion. Lectures are designed to supplement, not replace, the reading material, and to develop problem-solving skills. If you are not able to make class, notify the instructor before class. Unexcused absences may lower your final course grade. If you do miss class, it is your responsibility to find out what was covered and any administrative information that was discussed. Disruptive Behavior: While the University is a place where the free exchange of ideas and concepts allows for debate and disagreement, all classroom behavior and discourse should reflect the values of respect and civility. Behaviors which are disruptive to the learning environment will not be tolerated. As your instructors, we are dedicated to establishing a learning environment that promotes diversity of race, culture, gender, sexual orientation, and physical disability. Anyone noticing discriminatory behavior in this class, or feeling discriminated against should bring it to the attention of the instructors or other University personnel as appropriate. The following specific behavior is not allowed: • No cell phones or pagers in class. • No use of Laptops or other electronic devices for activity outside of its use in THIS class (i.e, surf the web, email, pictures) • No reading the Barometer during class • No eating during class Page - 5 - of 5 Cheating and Student Conduct: The instructors of this class take the issue of academic honesty very seriously. You are expected to be honest and ethical in your academic work. There is a “zero tolerance” policy in effect for cheating in this class. Any instance in which a student is caught cheating will be handled in strict accordance with the policies outlined at In order to provide students with a positive learning environment, OSU has adopted a pledge of civility, which can be found at Academic dishonesty is defined as an intentional act of deception in one of the following areas: • Cheating- use or attempted use of unauthorized materials, information or study aids • Fabrication- falsification or invention of any information • Assisting- helping another commit an act of academic dishonesty • Tampering- altering or interfering with evaluation instruments and documents • Plagiarism- representing the words or ideas of another person as one's own When evidence of academic dishonesty comes to the instructor's attention, the instructor will document the incident, permit the accused student to provide an explanation, advise the student of possible penalties, and take action. The instructor may impose any academic penalty up to and including an "F" grade in the course after consulting with his or her department chair and informing the student of the action taken. Students with Disabilities: Accommodations are collaborative efforts between students, faculty and Disability Access Services (DAS). Students with accommodations approved through DAS are responsible for contacting the faculty member in charge of the course prior to or during the first week of the term to discuss accommodations. Students who believe they are eligible for accommodations but who have not yet obtained approval through DAS should contact DAS immediately at 737-4098. ...
