	1	TRANSPORTATION OF PASSIVE SCALAR IN INHOMOGENEOUS TURBULENCE显示文摘The paper studies the transportation of passive scalar in the inho-mogeneous turbulence by means of large eddy simulation.The prediction accuracyis verified by the well-known Comte-Bellot spectrum of the homogeneous turbulence.The mean transportation properties are predicted with satisfaction and the underes-timation of the thermal flux by the phenomenological models has been disclosed.Thehigh intermittence of the temperature fluctuations has been found in the inhomoge-neous turbulence and it is the reason for the underestimation of turbulent thermalflux by the phenomenological model.	崔桂香陈宇光张兆顺许春晓 L.Shao J.P.Bertoglio	2000	Acta Mechanica Sinica2000，16，1：	3
	2	Effects of plane strain on inhomogeneous turbulence显示文摘The influence of the mean plane strain on the turbulence transportation is investigated by large eddy simulation (LES) in the shearless turbulence mixing layer. It is found that the mean strains enhance the turbulent fluctuations in the mixing region. Compression in the inhomogeneous direction can greatly increase the transport of turbulent kinetic energy by triple correlation terms, while stretching in the inhomogeneous direction decreases the turbulence transportation. The gradient diffusion models for turbulent transportation are evaluated and it is found that the inter-mittency consideration can improve the prediction ability of the gradient-type models for the triple correlation terms.	张兆顺崔桂香许春晓 L.SHAO H.Pascal J.P.Bertoglio	1999	Science China Mathematics1999，42，2：	1
