The inner surface of the channel is at a uniform temperature of 600 K and the outer surface is at a uniform temperature of 300 K. From a symmetrical elemental of the channel, a two-dimensional grid has been constructed as in the right figure below. The points are spaced by equal distance. Tout = 300 K k = 1 W/m-K T = 600 K (a) The heat transfer from inside to outside is only by conduction across the channel wall. Beginning with properly defined control volumes, derive the finite difference equations for locations 123. You can also use (n, m) to represent row and column. For example, location Dis (3, 3), location is (3,1), and location 3 is (3,5). (hint: I have already put a control volume around this locations with dashed boarder.) (b) Please use excel to construct the tables of temperatures and finite difference. Solve for the temperatures of each locations. Print out the tables in the spread…arrow_forward

The thermal conductivities are kA = 0.04 W/m/ºC, kB = 0.1 W/m/°C kc = 0.03 W/m/ºC, and kp = 0.06 W/m/°C. q T=370°C A B Area 0.1 m² Ꭰ -T= 66°C C 2.5cm → 7.5cm 5cmarrow_forward5-23 Consider steady one-dimensional heat conduction in a pin fin of constant diameter D with constant thermal conductivity. The fin is losing heat by convection to the ambient air at Too with a convection coefficient of h, and by radiation to the surrounding surfaces at an average temperature of Turr The nodal network of the fin consists of nodes 0 (at the base), 1 (in the middle), and 2 (at the fin tip) with a uniform nodal spacing of Ax. Using the energy balance approach, obtain the finite difference formulation of this problem to determine Tand T for the case of specified temperature at the fin base and negligible heat transfer at the fin tip. All temperatures are in °C FIGURE P5-23 Turr To Radiation e h, To Convectionarrow_forwardA flat plate in an ambient at temperature Tꝏ received from a source the net radiant heat flux q” (fig. 3-52). The thickness of the plate d is much less than its length 2L; the third dimension of the plate extends to infinity. The heat transfer coefficient from the ends of the plate, if needed, may be taken to be h3 ≠h1 ≠h2. Find the temperature distribution in the system.
