A transient time-marching technique is used in this paper for predicting turbulent flow and energy reversal in a bluff-body burner. It proposes a further modification of Boussinesq's hypothesis and the k-ε turbuleut model to calculate rationally turbulent properties and zones of energy reversal. The procedure used is based on a computer program with explicit scheme of simple 2-D turbulent flow. Fair agreement of the predicted values with the experimental data shows that the new form of the Reynolds...

A transient time-marching technique is used in this paper for predicting turbulent flow and energy reversal in a bluff-body burner. It proposes a further modification of Boussinesq's hypothesis and the k-ε turbuleut model to calculate rationally turbulent properties and zones of energy reversal. The procedure used is based on a computer program with explicit scheme of simple 2-D turbulent flow. Fair agreement of the predicted values with the experimental data shows that the new form of the Reynolds stress expression is more rational and may be applied to complex flows.

本文用非定常数值法研究了钝体燃烧器后的紊流参数分布和能量逆转,并对Boussinesq的雷诺应力模式和双方程k-ε紊流模型提出了改进方案。这样不仅计算出了能量逆转区,而且紊流参数分布也与实验相符。

This paper studies several typical turbulent flows with seperation by means of K-ε model and SIMPLER algorithm. One flow in a plane channel and another flow in a pipe both are obstructed by its own block. The two flows are simulated. The numerical results of the flows in a plane channel obstructed by a block are compare arid analysed with the present experimental data. The turbulent properties in the separated region are discussed and analysed theoretically. In order to improve the numerical results, the coefficient C_u of the standard K-ε model is adequately modified. New ideas and methods are adopted in the numerical methods and treating of boundary conditions.

Semiconductor pressure transducers were used to determine pressure radial distributions in a plexiglass column which was operated either as an air/tap water/glass beads three-phase fluidized bed or as an air/tap water two-phase bubble column. The characteristics of pressure radial distributions were compared for different axial locations under different operating conditions, and the turbulent properties of the systems were briefly discussed.
