ANALYSIS OF ENTROPY GENERATION FOR MIXED CONVECTION FLUID FLOW IN A TRAPEZOIDAL ENCLOSURE USING THE MODIFIED BLOCKED REGION METHOD
In this research, analysis of entropy generation for mixed convection fluid flow in a trapezoidal enclosure is numerically investigated. To achieve this goal, the influences of Grashof number, Reynolds number and inclination angle of enclosure side walls on the distributions of the velocity and temperature fields and the values of entropy generatio...

The Effects of Buoyancy Force on the Irreversibility of Three-Dimensional Step Flow in an Inclined Duct
This research deals with the study of the irreversibility of three-dimensional mixed convection flow in an inclined duct with step. To reach this goal, an analysis of entropy generation is carried out according to the second law of thermodynamics. The effects of buoyancy force on the flow irreversibility are analyzed with all details. The results s...

DEVELOPMENT OF THE MESHLESS LOCAL PETROV-GALERKIN METHOD TO ANALYZE THREE-DIMENSIONAL TRANSIENT INCOMPRESSIBLE LAMINAR FLUID FLOW
In this paper, a numerical algorithm is presented to simulate the three-dimensional transient incompressible flow using a meshless local Petrov-Galerkin (MLPG) method. In the proposed algorithm, the forward finite difference (FFD) and MLPG methods are employed for discretization of time derivatives and solving the Poisson equation of the pressure, ...
