| Abstract: | In the present work,the olive oil is taken as the working fluid to demonstrate the effects of fixed viscosity and temperature-dependent viscosity on the entransy dissipation in the parallel flow heat exchangers.When the fixed value of the viscosity is larger than the average value of the temperature-dependent viscosity,the entransy dissipation with fixed viscosity is smaller than that with temperature-dependent viscosity.However,the opposite conclusion may be obtained when the fixed value of viscosity is sm... |
