Kozeny carman permeability
Did you know?
The Kozeny–Carman equation (or Carman–Kozeny equation or Kozeny equation) is a relation used in the field of fluid dynamics to calculate the pressure drop of a fluid flowing through a packed bed of solids. It is named after Josef Kozeny and Philip C. Carman. The equation is only valid for creeping flow, i.e. in … Meer weergeven The equation is given as: $${\displaystyle {\frac {\Delta p}{L}}=-{\frac {180\mu }{{\mathit {\Phi }}_{\mathrm {s} }^{2}D_{\mathrm {p} }^{2}}}{\frac {(1-\epsilon )^{2}}{\epsilon ^{3}}}u_{\mathrm {s} }}$$ Meer weergeven The equation was first proposed by Kozeny (1927) and later modified by Carman (1937, 1956).
