Modeling and simulation of nanoparticle production in an aerosol flame reactor

Buddhiraju V.S., Nadimpalli N.K.V., Runkana V., TCS Research, Tata Research Development and Design Centre, A division of Tata Consultancy Services, IN

Aerosol flame synthesis is one of the commonly used methods for producing nanoparticles on a large scale. Large volumes of ultra-fine materials such as titania, silica, carbon black and zinc oxide etc. are produced in [...]

Guidelines for choosing an appropriate turbulence model when simulating blood flows in cardiovascular devices

Simpson B.A.F., Tansley G.D., Griffith University, AU

A systematic and detailed comparative study of computational results with validating experimental data has helped define the turbulence models that are most appropriate for predicting the velocity fields and shear forces in blood flows. The [...]
