Vortex Dynamics and Fluctuations of Impinging Planar Jet

Modeling and Computational Fluid Dynamics-Population Balance Equation-Micromixing Simulation of Impinging Jet Crystallizers

Computational fluid dynamics (CFD), micromixing modeling, and the population balance equation (PBE) are coupled to simulate the crystal size distribution in a confined impinging jet crystallizer. For the antisolvent crystallization of lovastatin in confined impinging jets, the simulation results show varying degrees of inhomogeneity in the supersaturation and the nucleation and growth rates in ...

High-Fidelity Simulations of Primary Breakup and Impinging Jet Atomization

Heat Transfer of an Impinging Jet on a Plane Surface

Abstract—A cold, thin film of liquid impinging on an isothermal hot, horizontal surface has been investigated. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for thin film flow. The approximate solution may provide a valuable basis for assessing flow and heat transf...

Prediction of turbulent heat transfer in impinging jet geometries

This chapter summarizes the current knowledge on the numerical prediction of turbulent impinging jet flows. The predictive capabilities of numerical models are evaluated by careful comparison with experimental fluid flow and heat transfer data. Turbulent fluctuations in the velocity field are mathematically modelled using the Reynolds Averaged Navier–Stokes (RANS) methodology. Turbulence is ass...

Vortex Fluctuations in Superconductors

The vortex fluctuations have proved to be responsible for the onset of dissipation in thin type-II superconducting Aims. There is also growing evidence that dissipation in hightemperature superconductors exhibits the same kind of two-dimensional (2D) behavior. However, a proper analysis of these materials requires a thorough understanding of the two-dimensional fluctuations. This thesis may be ...
