The Optimum Thickness of a Cooled Coated Wall Exposed to Local Pulse‐Periodic Heating

In the present work, the optimum thickness of a plane wall with a heat‐shielding coating that ensures the minimum steady‐state temperature of the most heated point of the wall is determined. On the unprotected side the wall is cooled by a medium whose temperature and heat‐transfer coefficient are constant, whereas on the side of the coating the wall is exposed to a heat flux with an intensity of the Gaussian type in the pulse‐periodic regime.
