Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

In this study, the paper introduces the surface roughness results of heat-treatment, and unheated-treatment SKD61 steel was processed by the EDM method with the participation of tungsten carbide powder. The least-square method was used to model the relationship between surface roughness of heat-treatment and unheated-treatment SKD61 steels, and these models were used to evaluate the role of each technological parameter, comparing the role of each technological parameter in the two models
The phenomenon of natural convection flow in a vertical cylindrical enclosure filled with unbound porous medium saturated by a Newtonian fluid has been investigated. The finite-difference method is performed to investigate the influence of uniform and non-uniform porosity along the z axis. The results of the numerical simulation obtained, presented in terms of streamlines, isotherms, local Nusselt number and average Nusselt number shows the dependence of the fluid flow pattern and the rate of heat transfer near to the heat wall on the variation of porosity is significant. The variation of the porosity along the z axis enhances the strength of fluid circulation. It is observed that the change from conduction dominant to convection dominant is obtained for low values of Rayleigh number in the case of variable porosity. Also, it is observed that an increase of Rayleigh number leads to an increase of the average Nusselt number while depending on the fluid flow pattern
