The experimental and numerical results reveal that the transverse flow of air stream through the punched holes disturbs the air flow in the lower channel, enhancing the heat transfer on the under surface of fin.
The results show that the interaction of the transverse rotating tertiary air and the vertically spouting flue gas causes a spirally rising gas-flow field.
The steady flow of non-Newtonian polymer solutions on their own and together with air transverse to a bundle of circular rods, has been studied experimentally.
The term SbCD body) can be replaced by the area of a flat plate transverse to the air stream that would produce an equivalent amount of drag, or Ae. Tucker19 deduced from experiments on living birds the formula Ae = (3.34 × 10−3)m2/3, where m is body mass (5 kg for Caudipteryx).
By trade-off the design requirements (maximum temperature rise, temperature uniformity, power requirement and cooling index), an appropriate solution in term of the optimal combination of the longitudinal interval, transverse interval, and air inlet width is obtained for the aligned arrangement.
