A small sphere of density rho, diameter D and heat generation gdot0 is exposed to a fluid at Tinf with a heat transfer coefficient h. Determine an expression for the steady-state temperature of the sphere, assuming isothermal behavior. At t = 0, the heat generation begins to display the transient decay gdot = gdot0*exp(-B*t) where gdot0 and B are constants. Derive an expression for the transient temperature response of the sphere, T(t). What is the final temperature of the sphere?

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
