基于谱方法的管内非牛顿流体非定常流动
Unsteady Flow of Non- Newtonian Fluid in Pipe by Spectral Method
摘要
Abstract
In the present investigation, the unsteady flow of upper - convected Maxwell fluid in a horizontal circularpipe is studied by spectral method. The unsteady problem is mathematically reduced to a partial differential equation ofsecond order. By using spectral method the partial differential equation can be reduced to a system of ordinary differen-tial equations for different terms of Chebyshev polynomials approximations. The ordinary differential equations are solvedby the method of Laplace transform and the eigenvaluemethod that led to an analytical form of the solutions.关键词
