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.

This work studies the thermal effect generated by the friction stir welding process through analysis of finite volumes applying remeshing techniques in welded joints of commercially pure aluminum AA1100. The modeling was realized using the physics properties of the welding material and the working tool in function to the temperature generated, considering the process variables, tool rotation speed, tool transverse speed, tool tilt angle and tool geometry. The solution methods were used through multiphysics to couple the behavior of the fluid mechanicals and the structural analysis in a transitory state. As a result, tool-workpiece interface temperature distribution profiles to different positions of tool transverse speed were obtained, showing an excellent approximation linked to the reconstruction of the mesh
The sedimentation in Kahayan River clearly influences the mobility in this river. The record that is carried out in Kahayan River can worsen the condition. Due to the important function of Kahayan River as the transportation facility, so it has to be carried out an effort to maintain the Kahayan river condistion itself. This research intends to build the total sediment transport modeling and it is conducted by using model test due to the prototype of Kahayan River is so long, wide, and depth. This modeling uses 4 variation of discharge such as Q10 = 0.489 l/s, Q23 = 0.728 l/s, Q50 = 0.797 l/s, and Q100 = 0.994 l/s by using river factual slope: 0.0019. The result shows that the 2 equation due to the analysis are close to the Shield amd Einstein equation. Besides it, the new equation that is obtained from the result of dimension analysis and then it is validated by the field data and the result is a new equation for the sediment discharge in Kahayan River is as follow: Q_s=(((V/(D^(1/2) g^(1/2) )) D^(5/2) g^(1/2))/3,6579)^(1/0,2466)
