VELOCITY DISTRIBUTION AND PREDICTION OF FRICTION FACTOR AND PRESSURE GRADIENT IN A TURBULENT POROUS TUBE FLOW WITH INJECTION OR SUCTION

[摘要] References(15)Cited-By(2)An expression of velocity distribution of Stevenson''s type is proposed for fully developed porous tube flow, on the basis of which the friction factor and the pressure gradient are analytically predicted. The prediction is in good agreement with the experimental results, but its applicability is restricted to a flow at mw<7.3 × 10-3.
