Conduction mode of heat transfer mainly depends upon the conductivity of the medium and the size of a gap at the interface.(a) True(b) FalseThe question was asked in unit test.My question is from Solidification with Predominant Interface Resistance in section Cooling and Solidification of Casting-Forming-Welding I |

Answer» RIGHT choice is (a) True Explanation: Conduction HEAT transfer depends on the conductivity of the medium and the gap size as well. Thus, the correct modeling of the heat transfer across the interface depends upon many factors like interface temperatures, surface characteristics, thermo-physical properties of the gap medium INCLUDING coating MATERIAL ETC. |
