2. LES stochastic modelling of cavitation with its applications in OpenFOAM
Abstract : Cavitation is a vaporisation process that commonly happens in high pressure injectornozzles nowadays. It has been shown by previous studies that cavitationhas a significant influence on the subsequent atomization process, the qualityof which would in turn heavily affect the quality of combustion.

3. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation
Abstract : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. READ MORE

4. Extension of OpenFOAM Library for RANS Simulation of Premixed Turbulent Combustion
Abstract : Unsteady multi-dimensional numerical simulation of turbulent flames is a well recognized tool for research and development of future internal combustion engines capable for satisfying stringent requirements for ultra-low emission and highly efficient energy conversion. To attain success, such simulations need, in particular, well elaborated Computational Fluid Dynamics (CFD) software, as well as advanced predictive models of turbulent burning. READ MORE

5. Plasma Arc Welding Simulation with OpenFOAM
Abstract : A simulation tool that is valid within the field of tandem arc welding(unsteady, three dimensional thermal plasma flow) has been developed,based on the open source CFD package OpenFOAM. The validation of the electromagnetic part of the solver has been done separately using a problem with a known solution. READ MORE
