The dependency of size of the entering intensity turbulence\u00A0on flux and heat transfer in the annalus canal of model of nuclear fuel cell will be determined. It will be monitored several mode. Modes with different size of entering intensity turbulence and further with different size of velocity in canal. During measuring distribution of the static pressure along canal, velocity profiles a intensity of the turbulence in entering cross-section will be determined. Further the local a general lossing coefficient will be determined from computation of local and mean values of heat transfer coefficient. The Nusselt, Stanton and Reynolds numbers will be determined. Further works will be focused on numerical simulation of first part of the model of fuel cell and it will be focused on numerical simulation of whole model of fuel cell. Numerical simulation will be provided for possibility of fast change of the geometry and thermophysical properties of"@en . " velocity profile" . . .
