Two papers presented at the 49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit are:
1. “Numerical Simulations of Instabilities in Single-Hole Orifice Elements,” by Vineet Ahuja, Ashvin Hosangadi, Matthew A. Hitt, and David M. Lineberry
An orifice element is commonly used in liquid rocket engine test facilities either as a flow metering device, a damper for acoustic resonance or to provide a large reduction in pressure over a very small distance in the piping system.
2. “Transient Simulations of Rotordynamic Problems with Whirling Motion,” by Chandrasekhar Kannepalli, Vineet Ahuja and Ashvin Hosangadi
A simulation framework based on the immersed boundary method (IBM) is proposed as a simple, efficient and viable solution strategy for the unsteady rotordynamic analysis of whirling shaft problems.
