The Eddy Dissipation Concept for turbulent combustion (EDC) was proposed 40 years ago by Magnussen [1]. With modest changes, it has been applied by engineers and scientists and validated against a wide range of
Using CFX to calculate the airfoil by changing the I (inlet turbulence intensity) and the inlet Re number, but the K (Turbulent Kinetic Energy), Epsilon (Turbulence Eddy Dissipation) calculated by the CFX are different from the results calculated by myself using the equations. ...

turbulence eddy dissipation rate hai all, i am modeling the fluidized bed column and i am including k-epsilon model for turbulence accounting, i want to calculte total energy dissipation rate in the whole column, but i don't know how do get this value through simulation please help me with...
It shows through the model test that sucking eddy,shock wave and energy dissipation exist in the original layout plan. 通过水工模型试验研究,指出了原布置方案中存在的吸气漩涡、冲击波、消能等问题,并在尽量利用现有工程设施的基础上,针对性地提出了经济合理、安全可行的优化布局措施,以确保工程泄洪安全。
采用低雷诺数kε模型与SIMPLEC算法计算通道内可压缩变物性气流的湍流对流换热,采用蒙特卡罗法求解通道壁面间的辐射换热。 2. The upper and lower bounds on the dissipation of time average heat transport potential ca- pacity in turbulent convection with volume heat source are determined mathematically,which re...
Although overall compressible dissipation contributes to less than one‐tenth of the total dissipation, compressible dissipation around shocklets is about an order of magnitude larger than typical values of incompressible dissipation. In the zones of eddy shocklets, pressure is highly correlated with ...
