CACTUS is a hydrokinetic turbine performance code under development at Sandia National Laboratories (SNL). Details on it capabilities are given in [1]. CACTUS simulates arbitrary geometries, including crossflow and axial flow rotors. SNL added new capabilities to CACTUS and an outreach effort was begun to solicit interest among MHK researchers and developers who want to consider CACTUS for hydr...

Recent developments in tidal energy converter technology and turbine array projects require fast and robust simulation tools. An important challenge is now estimating the power production for a array of machines as well as optimizing the placement within a grid. The most common method to do so is the coupling of momentum sources with a flow simulation. This method, called the actuator disc mode...

The present study explains a steady-state method of measuring convective heat transfer coefficient on the casing of an axial flow turbine. The goal is to develop an accurate steadystate heat transfer method for the comparison of various casing surface and tip designs used for turbine performance improvements. The free-stream reference temperature, especially in the tip gap region of the casing ...
