A CFD analysis of the effects of injection and suction through a perforated square cylinder on some thermo-fluid parameters

Mir Elyad Vakhshouri; Burhan ÇUhadaroğlu

Volume 11, Issue 1 , September 2021, , Pages 23-33


  The effects of uniform injection and suction through the surfaces of a perforated square cylinder on the vortex shedding, heat transfer and some aerodynamic parameters have been investigated numerically. The finite-volume method has been used for solving the Navier-Stokes equations for incompressible ...  Read More

Volume 9, Issue 1 , September 2019, , Pages 77-87


  The aim of our study is to analyze the impact of insertion holes in the middle of obstacles on the flow around a surface-mounted cube, In order to do this; we studied four configurations of obstacles in a channel with a Reynods number based on obstacle height ReH = 40000. The hexahedral structured meshes ...  Read More

Derivation of turbulent energy of fiber suspensions

S. F. Ahmed; M. S. A. Sarker Sarker

Volume 4, Issue 2 , June 2015, , Pages 155-163


  The energy equation for turbulent flow of fiber suspensions was derived in terms of second order correlation tensors. Fiber motion of turbulent energy including the correlation between pressure fluctuations and velocity fluctuations was discussed at two points of flow field, at which the correlation ...  Read More

Derivation of turbulent energy in a rotating system

S. F. Ahmed

Volume 3, Issue 1 , December 2013, , Pages 75-83


  Energy equation for turbulent flow in a rotating system was derived in terms of second order correlation tensors, where the correlation tensors were functions of space coordinates, distance between two points and time. To reveal the relationship of turbulent energy between two points, one point was taken ...  Read More
