Unformatted text preview: CBE 320 November 9, 2009 Transport Phenomena Problem Session XI Part A: Interphase Energy Transport 1. Solve the fin problem described in Section 10.7 using the equations of change derived in Chapter 11. Note that in order to obtain Eq. 10.73, the heat transfer from the faces must be incorporated into the energy equation (e.g., Eq. 11.210) as a source term. Obtain Eq. 10.73 using the equations of change from Chapter 11, and obtain the steadystate temperature distribution in the fin. 2. Work problem 14A.1 in BSL. 1 Solutions HW 11B Solutions (1.) The first step is to determine the source term, S . This is the rate of energy produced per unit volume. For the fin, this energy production is actually an energy loss rate from the fin faces. The term S must describe the rate of energy production from the faces, to the uid, per unit volume of fin material. To obtain this, consider a section of the fin z as we did in the shell balance. The energy production rate per unit volume isas we did in the shell balance....
