On the explicit analytic solution of Cheng-Chang equation. (English) Zbl 1029.76050
Summary: An analytic technique is applied to solve the free convection over a heated horizontal flat surface embedded in porous medium. An explicit analytic and uniformly valid solution is given to the so-called Cheng-Chang equation, which agrees well with numerical results.
