Plane Turbulent Jet Flow in a Favourable Pressure Gradient

SUMMARY An experimental study has been made of an incompressible turbulent plane jet exhausting downstream into an external flow having a favourable longitudinal pressure gradient approximating that of two-dimensional sink flow. Four flows were studied, for which the ratios of mainstream and jet velocities at the exit plane of the jet were in the range from 0.1 to 0.5. For each case velocity pr...

Transient Natural Convection in a Rectangular Cavity Filled with Porous Medium Heated Discretely at Vertical Wall

Numerical analysis is presented for transient buoyancy-induced natural convection from discrete heating inside a two-dimensional rectangular enclosure filled with porous medium. The study has been made for Rayleigh numbers of 100, 1000 and 10000 with an aspect ratio of 2. The left vertical wall is heated discretely to a constant high temperature and the right wall is cooled to a constant low te...

An LES/PDF study of a turbulent lifted ethylene jet flame in a heated coflow

We report a large-eddy simulation (LES)/probability density function (PDF) modeling study of a turbulent lifted ethylene jet flame in a heated air coflow, using a 22-species reduced chemical mechanism. In this flame, the central ethylene jet is ignited by the heated coflow, and the lifted jet flame base stabilization reaches a statistically stationary state. In this LES/PDF study, the filtered ...

Numerical Investigation of Heat Transfer Enhancement in a Rectangular Heated Pipe for Turbulent Nanofluid

Thermal characteristics of turbulent nanofluid flow in a rectangular pipe have been investigated numerically. The continuity, momentum, and energy equations were solved by means of a finite volume method (FVM). The symmetrical rectangular channel is heated at the top and bottom at a constant heat flux while the sides walls are insulated. Four different types of nanoparticles Al2O3, ZnO, CuO, an...
