  2. Transition Modeling • Problem Descriptions • Locate the position of transition over a wing • Solution Methodology • Transition is a very important phenomena in • aerospace and turbo-machinaryapplication • and quite challenging to predict. This becomes • more important for low Reynolds number airfoil • flows. It has a significant influence on skin friction • and separations. Here CFD is used in predicting • the transition location and increase in skin friction • drag due to transition. http://BEanalytic.com

  3. Flow simulation of filter • Problem Descriptions • Design of a new filter • Solution Methodology • The purpose of filters is to filter out small particles from the continuous flowing fluid. Designers need to go through several challenges to validate his filter design. • Today designer can get a detailed picture of filter working conditions using CFD porous modeling technique and finally get an optimal cost effective design. http://BEanalytic.com

  4. Pump Cavitation • Problem Descriptions • The pump isn't working properly and when • pump is taken apart and impeller is found to be • badly damaged. • Possible cause of the damage is Cavitation • Cavitation is a common occurrence in a pump but it involves • the most complex physics. Pump cavitation can be felt by noise • and vibrations and may likely can cause erratic power consumption • and fluctuations or reductions. It can spoil blade surfaces and also • cause of wear. • A multi-phase CFD method is used to analyze pump performance • under developed cavitating conditions. Characteristic performance • trends associated with off-design flow and blade cavitation are • observed. http://BEanalytic.com
