Abstract Computational Fluid Dynamics (CFD) is a useful tool for predicting flow in cases where experimental measurements can be difficult or costly to conduct, such as measuring the wake from…
Abstract Polymeric flocculants have been used to enhance the settling and thereby the separation process by which the particles mix with the flocculant to produce large porous aggregates which settle…
Abstract Recent years have witnessed a significant proliferation of numerical libraries being used in computational continuum mechanics. While the appearance of open source codes in general, is a positive development,…
Abstract Incompressible turbulence models have been implemented in Caelus, a general purpose numerical framework, to enable computations of turbulent incompressible flows. While other open source libraries and CFD solvers implement…
Abstract Cyclone separators play a dominant role in the industrial separation of dilute particles from an incoming gas flow. The incoming flow enters tangentially and accelerates on its way down…
Abstract Bluff body shapes are used to promote better heat and mass transfer in various industrial flow situations, flow past them serving to enhance turbulence and thereby promote mixing, primarily…
Abstract Turbulence is a phenomenon that occurs frequently in nature and is present in almost all industrial applications. Despite significant increase in computational power in modern processors, Reynolds averaged Navier-Stokes…
Abstract Bubble column reactors are widely used in the chemical and biochemical process industries, but numerous examples can be found in petroleum, pharmaceutical, agricultural, biochemical, food, electronic, and power-generation industries.…
Abstract Fast transient solution of incompressible turbulent flows still occupy a dominant place in engineering computations. Majority of the solvers that use finite volume method on unstructured meshes with the…
Abstract This paper presents a fast transient solver suitable for the simulation of transient turbulent flows. The main characteristic of the solver is that it is based on the projection…
Abstract For many industrial fluid dynamics problems, it is impractical to perform experiments on the physical world directly. Instead, complex, physics-based simulation codes are used to run experiments on computer…
Abstract Design optimization is becoming increasingly important in engineering practice. In particular, shape optimization is becoming an important part of the design process in internal and external vehicle aerodynamics. Reliance…
