在网上博客看到一个人总结的推导粘性阻力和内部阻力的方法,不知道这种方法正确吗,是否具有普遍性?大家来鉴定一下~
Experimental data that is available in the form of pressure drop against velocity through
the porous component, can be extrapolated to determine the coecients for the porous
media. To e ect a pressure drop across a porous medium of thickness, n, the coecients
of the porous media are determined in the manner described below.If the experimental data is:
Velocity Pressure Drop
(m/s) (Pa)
20.0 78.0
50.0 487.0
80.0 1432.0
110.0 2964.0
