Abstract:

Compact heat exchangers (CHE) improve the heat transfer rate with lighter weight and lower volume than other counterparts. An important point in CHEs is their higher pressure drop relative to conventional heat exchangers. This study aims to investigate the heat transfer rate and pressure drop in some proposed models of these heat exchangers with/without vortex... More

Abstract:

A comprehensive review of all the related investigations carried on water jet cutting or AWJ (AWJ) cutting is performed. The experimental methods and results used on this subject were examined, defined and compared by the researchers. This research shows that further improvements are possible in the water jet cutting method. In order to reduce the... More

Abstract:

The main focus of this study revolves around the problem of vibrations in unmanned aerial vehicles and aims to propose solutions using different designs of vibration dampers. Specifically, the study identifies the sources of vibrations in a Single Rotor Rotary Wing (Monocopter) type UAV. To assess the damping performance of the designed dampers, vibration tests... More

Abstract:

Reduced order model (ROM)-based controllers have proved to be effective to generate stable bipedal locomotion. However, it is important to understand the limitations and effectiveness of these models without implementing any controllers. This study highlights the versatility of the Linear Inverted Pendulum Model (LIPM) at various walking speeds. Firstly, the Centre of Mass (COM) trajectory... More
