in this study, mixed convection heat transfer and local and global entropy generation in aventilated square cavity have been investigated numerically. the natural convection effect isachieved by a constant heat flux imposed at the bottom wall and cooled by injecting a coldfollow. in order to investigate the effect of port location, four different placementconfigurations of the inlet and outlet ...

Conventional arterial-line filters commonly use a large volume circular shaped housing, a wetted micropore screen, and a purge port to trap, separate, and remove gas bubbles from extracorporeal blood flow. Focusing on the bubble trapping function, this work attempts to explore how the filter housing shape and its resulting blood flow path affect the clinical application of arterial-line filters...

In order to prevent the backward flow of piezoelectric pumps, this paper presents a single-active-chamber piezoelectric membrane pump with multiple passive check valves. Under the condition of a fixed total number of passive check valves, by means of changing the inlet valves and outlet valves' configuration, the pumping characteristics in terms of flow rate and backpressure are experimentally ...

The internally geared gerotor type of positive displacement machine is widely used for pumping applications, but can also be to achieve internal compression or expansion a working fluid. A further development this configuration the application helical twist inner and outer rotors. Previous studies have shown that decrease power transferred between rotors, increase relative maximum flow areas at...

..̂IJ Previous papers described the Phase IA tests of the Rocketdyne configuration of the Space Shuttle Main Engine (SSME) High Pressure Fuel Turbopump (HPFTP) turbine with rough coated flight engine rotor blades and with polished coated rotor blades at Marshall Space Flight Center (MSFC) . The testing involved using scaled performance parameters and model measurements to determine the performan...

Modern engines are cooled by complex air and liquid cooling systems that manage the flow of high temperature air, gases and coolants, and house critical thermal management components. Plastics, many supplied by DuPont, are playing an increasingly important role in key cooling system parts including thermostat and heater housings, outlet and inlet ports, valves, cross-overs, coolant pumps, water...

Motivated by capture and detection of airborne biological agents in real time with a cantilever biosensor without introducing the agents into liquids, we present the effects of inlet/outlet configurations of a homemade particle collector on the electrostatic capture of airborne 100 nm diameter nanoparticles under swirling gas flows. This particle collector has three different inlet/outlet confi...
