【 摘 要 】

Because of increased heat production or reduction in effective surface area for heat exclusion, modern electronic equipment typically confronts thermal critical difficulties. This most interesting difficulty may be overcome by either developing an optimal shape for refrigeration systems or increasing heat transfer characteristics. In this situation, nanofluid works well in resolving all of these challenges. The goal of this work is to investigate a 2D flow of nanofluid across a rocket engine with entropy generation and Bejan number. The first equations are converted to non-dimensional forms by utilizing similarity transformations and then solved by using the variational iterative method. Tables and graphs have been used to convey the idea of the relevant aspects affecting hydrothermal performance. The graphs of velocity and temperature profiles, entropy generation and skin friction, and the Nusselt number for the related parameters, are provided, and the logical and physical explanations behind them are underlined. To the best of the authors' knowledge, nobody has recently tried to investigate a 2D flow of a nanofluid across a rocket engine with entropy generation and Bejan number. Furthermore, the accomplishments of this study are unique, and the numerical findings have never been published by any scholar. The velocity profile increases with increasing estimations of melting parameter. The thermal profile is enhanced for growing magnitudes of the Eckert number. The entropy generation profile increases for the increasing values of the volume fraction of nanoparticles.
