Description Numerical investigations in three-dimensional internal flows PDF

Characteristics of turbulent and vortical flows around free surface piercing struts are numerically and experimentally investigated. Three dimensional Reynolds averaged Navier-Stokes and continuity equations are used for the numerical simulation. Internal flows of a low-specific-speed pump stage, having a mixed-flow impeller and a vaned bowl diffuser combination, have been investigated experimentally and numerically.

Air was used as the test fluid, and the internal flows were measured at various locations and under various by: Search term. Advanced Search Citation Search. Search term.

The aim of the Priority Research. The present paper analyzes numerically the entropy generation induced by forced convection in a canonical configuration. The configuration itself includes two well known fluid dynamic problems: (1) an external flow (flow around a cylinder, Kármán flow); and (2) an internal flow (flow between two concentric rotating cylinders, Couette flow).

In many daily engineering issues (e.g., cooling Cited by: 3. Recent investigations on three-dimensional numerical models for periodically fully-developed flow and heat transfer in anisotropic porous media have been reviewed in this chapter.

Discussion covers laminar flows around collections of spheres and cubes, laminar forced convective flows through a bank of cylinders in yaw, and turbulent flows.

Real flows are described by partial differential equations which cannot be solved analytically in the general case. By dividing a complex flow domain into a multitude of small cells, these equations can be solved in an approximate manner by numerical methods.

Because of their wide range of application, numerical flow calculations (“computational fluid dynamics” Author: Johann Friedrich Gülich.

Numerical and experimental investigations of multiphase flows were performed and different calculation models of multiphase flows were modified to adjust the real multiphase conditions [20,21,22,23,24,25].

Numerical simulations were carried out to study multiphase flows in supersonic : Guang Zhang, Guang Fei Ma, Heuy Dong Kim, Zhe Lin. A novel three-dimensional (3D) model based on Reynolds turbulence stress model (RSTM) closure of equations of carrier and particulate phases was elaborated for channel turbulent flows.

The essence of the model is the direct calculation of normal and shear components of the Reynolds stresses for the particulate phase similar to the carrier : P. Lauk, A. Kartushinsky, M.
