Entransy Dissipation Analysis and Heat Transfer Optimization
H.Y. Zhu and Z.Y. Guo
The concepts of entransy and entransy dissipation are used to optimize heat transfer enhancement. The entransy dissipation is a designate of the loss of heat transfer ability, just like entropy generation is proportional to the loss of work ability. The extremum entransy dissipation principle is developed using the method of weighted residual. For the volume to point conduction problem this principle is applied to obtain the optimum distribution of added high conductivity materials, which minimizes the average domain temperature.
Keywords: Entransy, entransy dissipation, heat transfer, optimization, heat conductivity, constructal theory.
