Non-Uniform Flow Field and Numerical Simulations of Unwatchable Groundwater Flow

Determining the Hydro-acoustic Characteristics of the Ship Propeller in Uniform and Non-uniform Flow

This research has been carried out to determine the marine propeller hydro-acoustic characteristics by Reynolds-Averaged Navier-Stokes (RANS) solver in both uniform and non-uniform wake flow at different operating conditions Wake flow can cause changes in pressure fluctuation and gas effect on propeller noise spectrum. Noise is generated by the induced trailing vortex wake and induced pressure ...

Numerical Study of Wave Propagation in a Non-uniform Flow

Numerical simulations of glottal flow

Features of glottal flow are visualized by numerical simulation, using a Navier-Stokes solver for two-dimensional, incompressible flow. Four different shapes of glottal passages are examined, for comparison to stationary model measurements. Results include pressure distributions leading to the forces acting on the vocal folds and illustrate entry pressure loss and exit recovery. Flow field imag...

Numerical Investigation of Flow Field of D87 Dual Fuel Engine

A newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. The main fuel would be natural gas and diesel oil as pilot injection. The importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...

Study of Chemically Reactive Flow and Heat Transfer in the Presence of a Uniform Magnetic Field

The effects of chemical reaction, thermal stratification, Soret and Dufour numbers on magneto-hydrodynamic free convective heat and mass transfer of a viscous, incompressible,and electrically conducting fluid on a vertical stretching surface embedded in a saturated porous medium are presented. A similarity transform is used to reduce the governing partial differential equations into a syste...
