Two identical aluminum plates with thickness of 30 cm are pressed against each other at an average pressure of 1 atm. The interface, sandwiched between the two plates, is filled with glycerin. On the left outer surface, it is subjected to a uniform heat flux of 7800 W/m2 at a constant temperature of 50°C. On the right outer surface, the temperature is maintained constant at 30°C. Determine the thermal contact conductance of the glycerin at the interface, if the thermal conductivity of the aluminum plates is 237 W/m∙K. Discuss whether the value of the thermal contact conductance is reasonable or not

Question
Two identical aluminum plates with thickness of
30 cm are pressed against each other at an average pressure
of 1 atm. The interface, sandwiched between the two
plates, is filled with glycerin. On the left outer surface, it is
subjected to a uniform heat flux of 7800 W/m2 at a constant
temperature of 50°C. On the right outer surface, the temperature
is maintained constant at 30°C. Determine the thermal
contact conductance of the glycerin at the interface, if the
thermal conductivity of the aluminum plates is 237 W/m∙K.
Discuss whether the value of the thermal contact conductance
is reasonable or not
