The present survey consists of numerical prevision of two turbulent jets with swirling in a combustion chamber. The simulation is based on numerical method of finite volumes and finite differences of Patankar. The mathematicalmodel used is two equations o... see more

Turbulent flows of emulsions are associated with the processes of breakage, coalescence and sedimentation of droplets of dispersed liquid. Mechanisms of these physical phenomena that form the equilibrium composition of the droplets of dispersed phase are ... see more

A new phenomenological model, the TP (Temperature Phase) model, is presented to carry out optimization calculations for turbulent diffusion combustion in a high-pressure common rail diesel engine. Temperature is the most important parameter in the TP mode... see more

In the present study, the problem of axisymmetric round free jet was numerically solved. The governing equations (continuity, momentum, energy and turbulence) were discretized using the finite volume method. In order to determine which models provide the ... see more

The rough model method (RMM) is explained through its application to the design of a pressurized pipe-weir, widely used in practice. The three basic equations of turbulent flow are firstly applied to define explicitly the geometric elements of a referenti... see more

La mayor parte de las investigaciones que se han realizado sobre la convección natural han abordado su estudio en la región laminar y no se ha dirigido mucha atención a la convección natural turbulenta que suele presentarse cuando el número de Rayleigh su... see more

The Berre lagoon (France) is a semi-enclosed basin with 6 m of mean depth and 155 km2 of surface area. Due to the Durance river discharge in the north and the Mediterranean sea intrusion in the south, the hydrological situation is often strongly stratifie... see more

This paper presents development of k-e turbulence model which can be applied for non-homogeneous two-phase turbulent flows. The improvement of governing equations of k-e turbulence model is based on the decomposition of the two-phase flows into the gas ph... see more
