Mathematical modelling of thermal state of attachment of the tubes in tube plates in gas-tube boilers

The factors affecting the thermal state of attachment of the tubes in tube plates of gas-tube boilers are considered. For heat carriers the models of turbulent flow of compressible and incompressible liquids are used. The task on the exploration of hydro- and thermodynamic processes is solved by using the bundled software Ansys CFX. The recommendations on the consideration of the thermal state of the elements of boilers in designing are given.
