Consider a laminar 2-dimensional steady-state non-adiabatic flow through a short (from A to B = 2m) conical duct (see figure below). Inlet air is at 20C and all inside surfaces are at 100C. >11111 B T=20C T=100C a) Since the cone shape will change the direction and magnitude of the flow, indicate which point (A or B) is with the larger shear stress? The larger normal stress? Explain your answer using your knowledge in the Momentum Equations? b) Which terms in the heat transfer equation below exist (indicate all non-zero terms) for the above example? Consider all non-zero terms and rank them from the largest to the smallest (hint: what is the common unit here?). pcrf T . o'T 22T 02T +V +V, +V, -) =k +k +k at ox Oy az x? oy? z +0+9 1
