Incidents of partial or total thrust loss at cruise due to engine icing (mainly ice crystals and super-cooled water droplets at altitudes greater than 10,000 feet) have been recorded over the past several years. As air traffic continues to increase i

Some issues of He-Chen-Zhang lattice Boltzmann equation (LBE) method (referred as HCZ model) (J. Comput. Physics 1999; 152:642-663) for immiscible multiphase flows with large density ratio are assessed in this paper. An extended HCZ model with a filt

Incidents of partial or total thrust loss due to engine icing at cruise have been recorded over past several years. These events increase the demand for better understanding of compressor dynamics under such conditions. In the present study, physics

Propulsion system instabilities such as compressor surge and stall can arise due to ice ingested by an aircraft engine flying through high ice water content regions. Performance and operability are affected by ice ingestion into a gas turbine engine

Simulation of ice shed into a multistage axial compressor involves a coupled two phase flow of a continuous phase comprising of air and water vapor and a discrete phase with ice crystals and water droplets. A first principles based discrete phase mod

The HCUSP schemes being in an artificial dissipation form are more amenable to implementation in central difference codes than AUSM family of schemes. However, AUSM family of schemes has several attractive properties over H-CUSP, e.g. capturing conta

Numerical simulations of flows involving moving boundaries are challenging as they need to address the location and the conditions of the interface that interacts with the flow field. We have developed a unified, marker-based approach, which can trea
