| Abstract: | Heat exchange between a linear heat source and a gas flow is studied theoretically. The coefficient of source-to-gas heat transfer is found as a function of the gas velocity in the limit of zero temperature drop. It is shown that the heat-transfer coefficient depends linearly on the gas flow velocity for Peclet numbers 0.1–1.0. |
