A number of methods has been developed for calculation of heat transfer in the vertical round tube under conditions of forced convection with uniform heat flux at wall.
I would like to express hereby one of applications of this study in the design of heat exchanger instruments for water flow at 15.8℃(Pr=8) used frequently in our daily life.
Also all the results are investigated for forced convective heat transfer in the case of heated water flow at uniform wall heat flux in the vertical round copper tube, where the ratio of length to diameter will be 44.
They are well in agreement with Gratz and Kraussold equation respectively in laminar and transition flow range. In turbulent flow in the range from Re=10,000 to 65,000, the experimental formula is show as follows ; Nu=0.023 Re^(0.514) Pr^(0.4). And this is agreed with Dittus-Boelter equation when Reynolds number exponent increases from 0.80 to 0.814.
