Construct a 2-d numerical analysis of a rectangular-cross section turbine blade (k= 17 W/m.K) that has an internal cooling channel, example is shown in the below sketch. 24 in 2 in 2 in 10 in 3 in 3 in 9 in The exterior of the blade is exposed to superheated steam (700 C) with h=640 W/m.K and the channels are carrying flowing coolant (oil) at room temperature (25 C). It is required that the maximum temperature of the blade does not exceed 350 C. Determine the oil heat transfer coefficient needed to meet the temperature limit.
