Study of convective heat transfer with a time-variable rate of heat exchange
Abstract
The unsteady regime of heat conductivity in a gas-solid system with time-variable parameters is studied. A solution is obtained for the differential equation of heat conductivity in partial derivatives with third-order boundary conditions modified by the variable parameters. It is shown that when this solution is applied to concrete cases, good agreement is obtained with theoretically expected characteristics of time-dependent temperature changes.
