Apr 16, · I simulated a heat rejection problem using the rke model, which gave me an overestimated turbulence intensity, as high as 50%, and also consequently an overestimated effective fluid thermal conductivity. By looking at the high turbulence intensity level and the unrealistic temperature profile, it can be tell the model is not doing well. respectively (Fig. 2). Variations of the statistical means and rms values with sample size for the two components of the velocity vector are obtained for a line of measuring points along y axis at the mid-section of the domain. The turbulence intensity levels vary between % along this line. The x and y components of the velocity vector. Effect of turbulence intensity on the pressure drop and heat transfer in a staggered tube bundle heat exchanger. The effect of turbulence intensity on pressure drop and heat transfer was studied. For the non-isothermal measurements the Reynolds number took values from to and the turbulent intensity ranged from % to 3%. The Cited by: 9.

the study were (1) to obtain heat-transfer and boundary layer measurements with- in the cylindrical inlet and convergent portions of the nozzle and to apply the results in the evaluation of various heat-transfer prediction methods and (2) to observe the effects of upstream turbulence on nozzle heat-transfer rates and boundary layer profiles.

The measurements of the turbulent burningvelocity were based on setting the mean axial velocity u¯ up-stream of the turbulent ﬂame brush equal to the burning velocity. The turbulent burning velocitywas found to be proportional to the turbulence intensity and did not show a bending behavior that has been found by many other authors previously. Mean Flow and Turbulence Measurements in a Turbulent Free Cruciform Jet parameters such as inverse mean axial velocity decay, turbulence intensity, turbulent kinetic energy, and streamlines. High intensity, large scale turbulence was generated in a simulated combustor. Turbulence levels of up to 19 percent were reached. Heat transfer from a flat plate turbulent boundary layer was determined using three constant temperature cylinders with a 4 to 1 diameter range.
