Engineering Physics Annotation << Back THE PROBLEM OF NON-STATIONARY HEAT EXCHANGE OF LAMINAR FLOW IN THE INJECTION WELL O.V. AKHMETOVA, M.A. ZELENOVA, V.K. MUKHUTDINOV The problem of unsteady heat exchange in an injection well surrounded by a homogeneous orthotropic medium is considered. The task is complicated by taking into account the radial velocity profile of the injected fluid. Heat transfer at the well-media boundary is specified using interface conditions. Analytical asymptotic solutions of the problem under consideration are given for the average over the cross section temperature and for its radial distribution. Using a computational experiment, it was shown that the inversion range and the temperature range of the fluid signal increase with increasing receptivity of the injection well. Key words: temperature, injection well, orthotropic medium, non-stationary heat exchange, interface conditions, asymptotic method.
