We prove the existence and uniqueness of solutions to a nondegenerate problem. (without, zones of stagnation of gas temperature or velocity). The asymptotic behavior of these solutions is also studied.engjournal articlehttp://www.springerlink.com/content/a227t01x326535qt/fulltext.pdfhttp://www.springerlink.com/restricted access517.95diffusionmodelheatsystems of nonlinear degenerate parabolic equationsdiffusion couplingtemperature gas jetsasymptotic behaviorEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
