Experimental study and numerical simulation of three dimensional two phase impinging jet flow using anisotropic turbulence model
Hydrodynamic of a turbulent impinging jet on a flat plate has been studied experimentally and numerically. Experiments were conducted for the Reynolds number range of 72000 to 102000 and a fixed jet-to-plate dimensionless distance of H/d=3.5. Based on the experimental setup, a multi-phase numerical model was simulated to predict flow properties of impinging jets using two turbulent models. Mesh...
متن کاملExperiments and Numerical Simulations of Horizontal Two Phase Flow Regimes
Stratified two-phase flow regimes can occur in the main cooling lines of Pressurized Water Reactors, Chemical plants and Oil pipelines. A relevant problem occurring is the development of wavy stratified flows which can lead to slug generation. In the last decade, the stratified flows are increasingly modelled with computational fluid dynamics (CFD) codes. In CFD, closure models are required tha...
متن کاملNumerical modeling of subgrid heterogeneity in two phase flow simulations
[1] A coarse-scale model governing two-phase viscous dominated flow in heterogeneous porous media is presented. The coarse-scale water transport equation (or saturation equation) is derived from a volume average of the underlying fine-scale saturation equation. A key component of the coarse-scale description is the subgrid model, which appears in the formulation as a nonlinear, nonlocal term in...
متن کاملA Numerical Study of Dynamic Detonability Characteristics of Two-phase Unconfined Fuel-Air Clouds
A numerical simulation has been carried out to study the detonability characteristics of two- phase unconfined clouds. The parameters equivalence ratio, turbulence, shape, volume and uniformity of the cloud and the delay time distribution are recognized and introduced as the most important factors determining the reactivity of the cloud and influencing the initiation of a successful detonation....
