Engineering Physics Annotation << Back Modeling of Heat and Mass Transfer Processes During Depressurization of Transporting Fittings in Porous Media Khvostov A.A., Ryazhskikh V.I., Drozdov I.G., Ryazhskikh A.V., Slyusarev M.I. An approach to the development of a mathematical model that formalizes heat and mass transfer processes that occur during depressurization of transport fi ttings localized in a porous medium is considered. The main constitutive relations of the model include equations of conservation of energy and mass, which describe the hydrodynamics of non-isothermal fl uid fl ow in a porous medium, taking into account heat exchange with the environment. A series of computational experiments revealed the main factors influencing the sensitivity of the thermal imaging method for monitoring the depressurization of transport fittings using temperature signatures on the surface of the objects under study. The developed model can be used to justify and select technical solutions when developing thermal imaging systems for monitoring the condition of conveying fittings in porous media.
