PROGRESS IN THE STUDY OF NONLINEAR TURBULENCE MODELLING

1995, 25(3): 318-328. doi: 10.6052/1000-0992-1995-3-J1995-013

Abstract(1882)

PDF(1351)

Abstract:
Contemporary turbulence modelling research has been developed beyond the claasical concepts of Boussinesq eddy-viscosity and linear Reynolds-stress transport,the nonlinear nature of turbulent flolws is now one of the focal points of researcher's concern. The purposc iS to dcvelop the turbulence model which can simulate for modelling studics the complexity of turbulcnce motion more rcalistically, and to increase the adaptivity of the model in applications. Significant progress has heen made over the last fe...

PROGRESS IN THE STUDY OF TRAFFIC FLOW THEORY

1995, 25(3): 343-356. doi: 10.6052/1000-0992-1995-3-J1995-015

Abstract(2769)

Abstract:
Traffic difficulties have become a general perplexed problem in thedevelopment of large citics, so it is urgent to develop an effective theory oftraffic floty in order to workout a solution of the problem. In this paper, theprogress and up-to-date status of the investigation of traffic flow theory arereviewed in two main aspects, i.e., the dynamical analysis of traffic flow andthe models deseribing junction delays.Various related mathematical and dynamicalmodels are also listed and their validation and limi...

STUDY OF TRANSPORT AND FATE OF CONTAMINANTS AND BIODEGRADATION IN NONHOMOGENEOUS ACQUIFER

Abstract(1450)

PDF(1084)

Abstract:
In this paper, the biochemical and dynamical processes of chemical substance and biomass in contaminated ground water are presented. As an example,a mathematical model to quantify the interaction and movement of organism and bacteria in nonhomogeneous ground water flow is developed. Some important problems such as large gradient and different characteristic time occurring in the governing equations are briefly described, which is important for numerical modelling.
