Michelle Abercrombie, Jerry Lazarte, Emanuel Romero, Jaimy Schlesing, Alex Springer ENGR. 102 section1 Team #7 Project #1 Report Due Date: November 6, 2007 Operation Alpha Abstract: The purpose of the experiment was to design a completely solar-powered oven utilizing and changing the equations and constraints of a general solar oven design (found in the yellow book). The most important team goal desired as a result of the experiment was for the solar oven to reach a temperature of 450 ̊ F in a rough time of about 30-50 minutes (the total length of the class). A key constraint was designing the oven to work at the time of the class, 9:30 a.m. to a time of 10:20 a.m. Other criterion for this experiment was to maximize the difference between the inside and outside temperature of the oven while minimizing the cost of the materials that were used in its construction. There were specific materials provided to the team for the construction, which comprised another constraint. Another key concept was to go through a thorough design process and repeating it to achieve the desired results and understanding of concepts surrounding the experiment.

Michelle Abercrombie, Jerry Lazarte, Emanuel Romero, Jaimy Schlesing, Alex Springer Introduction: The objective of operation alpha is to design a solar oven with certain constraints to achieve the cheapest possible price and reach the highest possible temperature with these constraints. There are three types of heat transfer that one can use to their advantage in this project. Firstly, the derived theory will be shown to show how the team worked out the dimensions of the oven design taking into account the constraints presented before the project. The oven was constructed of three main parts. The shell, which was used to prevent the ambient temperature from reducing the internal temperature, or heat loss through convection, was the outermost part of the oven. The innermost part of the oven, called the chamber, is constructed to hold the items to be placed in the oven, yet still achieve and maintain a temperature of 450 or higher (Fahrenheit). The third piece of the oven is the reflectors, which are used to funnel the sun’s rays down into the chamber of the oven.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
