1. Mechanistic Modeling of Annular Flows at Near-Dryout Conditions
Abstract : This work aims at advancing the modeling methodology for near-dryout annular flows using two different computational fluid dynamics (CFD) approaches. One is termed as the transported film approach, where the film flow is separately modeled by a simplified liquid film model and then coupled with the gas core simulation using various closures.

2. Optimization of the Flow Process in Engine Bays - 3D Fan Modeling Strategies
Abstract : In todays automotive industry there is an apparent need and demand for low fuel consuming vehicles. This is a fact every automotive OEM is aware of and the heavy duty truck industry is no exception. With a cooling fan in today’s trucks that typically consumes of the order of magnitude 50bHp fully engaged - reducing this loss is very important. READ MORE

4. On Film Cooling of Turbine Guide Vanes : From Experiments and CFD-Simulations to Correlation Development
Abstract : To achieve high thermal efficiency in modern gas turbines, the turbine-inlet temperature has to be increased. In response to such requisites and to prevent thermal failure of the components exposed to hot gas streams, the use of different cooling techniques, including film cooling, is essential. READ MORE

5. Experimental and numerical investigations of underhood flow for vehicle thermal management
Abstract : Electrified vehicles are an essential part in reducing emissions from the transportation sector. Their development comes with a variety of new challenges. Most of them revolve around the energy efficiency of the vehicles as it directly relates to the range that can be covered with one charge. READ MORE
