	1	AN INVESTIGATION OF TURBULENT RECTANGULAR JET DISCHARGED INTO A NARROW CHANNEL WEAK CROSSFLOW显示文摘A computational investigation of the mean flow field of turbulent rectangular jets issuing into a narrow channel crossflow is presented. The length of the jet slot spans more than 55% of the crossflow channel bed, leaving a small clearance between the jet edge and sidewalls. A finite volume code employing the standard k-ε model is used to predict the mean, three-dimensional flow field. The mean flow field is investigated for two velocity ratios (6 and 9). Important flow features, such as the formation of different vortical structures and their characteristics owing to different values of the velocity ratio, are discussed. Some predicted results are compared with the experimental data reported in the literature. The predicted mean and turbulent flow properties are shown to be in good agreement with the experimental data.	PATHAK Manabendra DASS Anoop K. DEWAN Anupam	2008	Journal of Hydrodynamics2008，20，2：	5
	2	A MULTIGRID-ACCELERATED THREE-DIMENSIONAL TRANSIENT-FLOW CODE AND ITS APPLICATION TO A NEW TEST PROBLEM显示文摘A multigrid-assisted solver for the three-dimensional time-dependent incompressible Navier-Stokes equations on graded Cartesian meshes is developed.The spatial accuracy is third-order for the convective terms and fourth-order for the viscous terms,and a fractional-step strategy ensures second-order time accuracy.To achieve good time-wise efficiency a multigrid technique is used to solve the highly time-consuming pressure-Poisson equation that requires to be solved at every time step.The speed-up achieved by multigrid is shown in tabular form.The performance and accuracy of the code are first ascertained by computing the flow in a single-sided lid-driven cubic cavity with good grid-economy and comparing the results available in the literature.The code,thus validated,is then applied to a new test problem we propose and various transient and asymptotically obtained steady-state results are presented.Given the care taken to establish the credibility of the code and the good spatio-temporal accuracy of the discretization,these results are accurate and may be used for ascertaining the performance of any computational algorithm applied to this test problem.
