Consider the thermal conduction module and operating conditions of Problem 4.76. To evaluate the transient response of the cold plate, which has a thermal diffusivity of a = 75 X 10-6 m2/s. assume that when the module is activated at t = 0, the initial temperature of the cold plate is T1 = 15°C and a uniform heat flux of q"o = 105 W/m2 is applied at its base. Using the implicit finite-difference method and a time increment of ∆t = 0.1 s, compute the designated nodal temperatures as a function of time. From the temperatures computed at a particular time, evaluate the ratio of the rate of heat transfer by convection to the water to the heat input at the base. Terminate the calculations when this ratio reaches 0.99. Print the temperature field at 5-s intervals and at the time for which the calculations are terminated.
