Abstract: One of the innovative ways to improve heat transfer properties of heat exchangers, is using nanofluids instead of traditional fluids. Due to presence of metal and oxides of metal particles in nanofluids structure, they have better potential in different environments and conditions than conventional fluids and having higher thermal conductivity causes improvements in heat transfer properties. In this research flow of two different nanofluids... More

Abstract: Fused deposition modeling (FDM) is one of the most adaptable additive manufacturing method owing to the cost-effectiveness and environment-friendly nature. However, FDM technique still possesses major difficulties in terms of poor surface quality because of adding layer by layer manufacturing process for the prototypes. It is desirable to explore an efficient technique for FDM parts to enhance the poor surface quality and dimensions precision.... More

Abstract: It is well-known that suspension systems plays a major role in automotive technology. Most of the today’s vehicle applies a passive suspension systems consisting of a spring and damper. The design of automotive suspension have been a compromise between passenger comfort, suspension travel and road holding ability. This work aims in reducing the suspension travel alone by developing a quarter car model suspension for a passenger car to improve... More

Abstract: In some data centers, cold air is required to act on the cabinet to achieve cooling requirements, and the mixing of cold air and hot air reduces the utilization efficiency of cold air. In order to solve this problem, a jet cooling model is established to solve the optimal position of the outlet through the movement of cold air. More
