For the turbulent developing flow of absorbing and isotropic scattering medium in a circular tube, the steady state heat flux of the coupled heat transfer of turbulent convection and thermal radiation under constant wall heat flux was investigated numerically.

At the centre of the section near the top of burners,its rising velocity is minimum,its turbulence kinetic energy is maximum,and its temperature is maximum too.

Then the result of turbulence kinetic energy of numerical simulation near the roof in the 90°　direction was present,which was used to analyse the rule of distribution of fluctuating wind pressure on the cantilever.

By performing a number of experiments on the turbulence kinetic energy of smooth plate surfaces and different V-riblet surfaces in various sizes at different wind velocities,the distributing rule of the turbulence kinetic energy over the riblet surfaces in the boundary layer is acquired.

The varying rule of vertex center depth and the distribution of turbulent kinetic energy in the mould have been studied when the structure and size of submerged entry nozzle(SEN) and processing parameters are changed.

The static pressure,turbulent kinetic energy, streamlines distributions and external performance were analyzed and compared.

In order to study the interaction between two spheres and the effect of different space on wake and turbulent kinetic energy,numerical simulations on five cases between L=2.

Average velocity and turbulent kinetic energy k distribution were obtained.

Based on the tendency equation of turbulent kinetic energy, its simplified equation including only wind shear and air stability was derived.

The distribution of Reynolds shear stress and turbulent kinetic energy was described and the correlation of these two quantities was discussed.

), turbulence kinetic energy and sensible heat flux are calculated and their characters are analyzed under different stability and compared with the r.
