Scaling analysis heat transfer
WebThe objective in analyzing internal flow heat transfer depends on the thermal boundary condition. (i) Uniform surface temperature. In this class of problems we seek to determine axial variation of the following variables: (1) Mean fluid temperature (2) Heat transfer coefficient (3) Surface heat flux (ii) Uniform surface flux.
