flat-plate solar collector

8.17    A flat-plate solar collector is used to heat atmospheric air flowing through a rectangular channel. The bottom surface of the channel is well insulated, while the top surface is subjected to a uniform heat flux qo", which is due to the net effect of solar radiation absorption and heat exchange between the absorber and cover plates.

(a)    Obtain expressions for the local heat flux q"(x) and the total heat transfer q from the fuel rod to the water.

 

(b)    Obtain an expression for the variation of the mean temperature Tm(x) of the water with distance x along the tube.

 

(c)    Obtain an expression for the variation of the rod surface temperature Ts(x) with distance x along the tube. Develop an expression for the x-location at which this temperature is maximized.

(a)    Beginning with an appropriate differential control volume, obtain an equation that could be used to determine the mean air temperature Tm(x) as a function of distance along the channel. Solve this equation to obtain an expression for the mean tem- perature of the air leaving the collector.
