A drop impingement on a hot surface is known as an effective way for heat removal. The present work uses VOF (volume of fluid) model to simulate the flow behavior and temperature distribution 50 °C heated plate while relatively cold water impinging. at zone used examine transient transfer coefficients using single double drops conditions. spreading factor tested in both cases. test rig built ve...

Abstract In almost every industry, polymer materials are in high demand recent years due to their lightweight and easy formability. However, eco-friendly, cost-efficient defect-free joining of polymers is a major concern. this article, novel approach taken for friction stir welding polypropylene by implementing double-side technique. The effect tool rotational speed on construction properties t...

Abstract. The titanium alloy hollow lattice structures can be widely applied on the advanced aircrafts due to their excellent mechanical properties and light weight. Superplastic forming diffusion bonding (SPF/DB) process is an manufacture these with two outer plates one inner plate. To further decrease weight of structures, thinner plate preferred when compared plate, however, it would result ...
