Optimizing naturally driven air flow in a vertical pipe by changing the intensity and location of the wall heat flux

M. Rahimi; M. Khalafi-Salout

Volume 5, Issue 2 , June 2016, Pages 137-145


  Heat transfer from the internal surfaces of a vertical pipe to the adjacent air gives rise to the air flow establishment within the pipe. With the aim of optimizing the convective air flow rate in a vertical pipe, the details of the flow and thermal fields were investigated in the present study. Conservation ...  Read More

Research Paper Meshless Numerical Methods
Incompressible laminar flow computations by an upwind least-squares meshless method

M. Y. Hashemi

Volume 5, Issue 2 , June 2016, Pages 147-160


  In this paper, the laminar incompressible flow equations are solved by an upwind least-squares meshless method. Due to the difficulties in generating quality meshes, particularly in complex geometries, a meshless method is increasingly used as a new numerical tool. The meshless methods only use clouds ...  Read More
