- The Air Moving With Horizontal Velocity Of Is Transporting Heat From A Plate With Length Of L 0 Im And Heat Generation O 1 (176.33 KiB) Viewed 28 times
The air moving with horizontal velocity of is transporting heat from a plate with length of L=0.im and heat generation of 500 w/mº, as shows in figure below. The left boundary is subjected to a constant temperature of 12°C, and right boundary of the plate is insulated. Given that the width of the plate is sufficiently large, the temperature distribution between two boundaries can be consider as one-dimensional problem, and is govern by following equation: d(put) ()+S S500 W/m T = 12°C 0.1 m Where is the rate of heat generation. The air density is given as p=1 kg/m3, and k=0.01 W/m.K. velocity u=0.5 m/s. By using 4 finite volumes: (a) Calculate what is the Peclet number of this problem (b) Formulate the equation for interior control volumes using finite volume method to solve for the value of temperature. The equation can be written as awTw+Ap Ip+QĘTe=b. What will be the value of ap/aw? (beware about positive and negative sign)
