The physical properties of the fluid remain constant, notably its specific mass, its dynamic viscosity and its thermal diffusivity. The nondimensional parameters which the solutions of the problem depend on are defined. A numerical integration using the shooting method is applied for solving the Navier\u2013Stokes equations and the energy equation. Bifurcation diagrams are presented and enable to highlight significant properties of the flow. Some thermal behaviors corresponding to specific values of the parameters are performed. Asymmetric solutions of the steady flow are described and some results about velocity components are also analyzed. <\/jats:p>","DOI":"10.1142\/s0218127409024566","type":"journal-article","created":{"date-parts":[[2009,12,15]],"date-time":"2009-12-15T11:45:55Z","timestamp":1260877555000},"page":"2939-2951","source":"Crossref","is-referenced-by-count":6,"title":["DYNAMIC BEHAVIOR OF A STEADY FLOW IN AN ANNULAR TUBE WITH POROUS WALLS AT DIFFERENT TEMPERATURES"],"prefix":"10.1142","volume":"19","author":[{"given":"JACQUES","family":"HONA","sequence":"first","affiliation":[{"name":"Applied Mechanics Laboratory, Faculty of Science, University of Yaound\u00e9 I, P.O.
