Abstract: Current heat transfer fluids for concentrated solar power applications are limited by their high temperature stability. Other fluids that are capable of operating at high temperatures have very high melting points. The ...

Abstract: Cavitation produces undesirable effects within turbines, such as noise, decreases in efficiency, and structural degradation of the device. Two microhydro turbines incorporating Archimedean spiral blade geometries were ...

Abstract: One of the major challenges preventing the concentrated solar power (CSP) industry from occupying a greater portion of the world's energy portfolio are unattractive start up and operating costs for developers and investors. ...

Abstract: Computational fluid dynamics (CFD) and heat transfer simulations are conducted for a novel heat exchanger. The heat exchanger consists of semicircle crosssectioned tubes that create narrow slots oriented in the streamwise ...
