Description:

An analytical solution for the creeping flow of an inelastic fluid past a solid sphere has been obtained using an empirical 3-parameter fluid model. The governing equations of motion have been solved aproximately using a perturbation approach. Expressions have been obtained for the Stokes stream function and the drag experienced by the stationary sphere. It is shown that the drag for the non-Newtonian fluid is greater than the one predicted by the classical Stokes formula. and Použitím trojparametrického empirického modelu tekutiny sme získali analytické riešenie pomalého prúdenia neelastickej tekutiny okolo pevnej gule. Pohybové rovnice boli riešené približne metódou malých rozruchov. Získali sme vzťahy pre výpočet Stokesovej prúdovej funkcie a pre odpor stojacej gule. Bolo ukázané, že tento odpor z obtekania je pre nenewtonskú tekutinu väčší, ako vyplýva z klasického vzťahu Stokesa pre newtonskú tekutinu.
