Acylindrical fuel rod (k 5 30 w/m∙k) of 2 cm in diameter is encased in a concentric tube and cooled by water. the fuel rod generates heat uniformly at a rate of 100 mw/m3 , and the average temperature of the cooling water is 75°c with a convection heat transfer coefficient of 2500 w/m2 ∙k. the operating pressure of the cooling water is such that the surface temperature of the fuel rod must be kept below 200°c to avoid the cooling water from reaching the critical heat flux (chf). the critical heat flux is a thermal limit at which a boiling crisis can occur that cause overheating on the fuel rod surface and lead to damage. determine the variation of cen98187_ch02_p067-141.indd 133 14/02/14 3: 01 pm 134 heat conduction equation temperature in the fuel rod and the temperature of the fuel rod surface. is the surface of the fuel rod adequately cooled?
