| Abstract: | In this peper,an experimental study of fully developed turbulent air flow in rectangular channel of narrow aspect ratio with two opposite rib-roughed walls was performed to determine the effect of the rib pitch-to-height on friction factor and heat transfer coefficients with low Renolds number.A general Prediction method is given for average friction factor and average Stanton number in rectangular ducts.The result can be used in design of low flow radiator. |
