Title of the articleNumerical calculations of heat transfer processes in the individual nodes multilayer walling
Abstract.In the article «Numerical calculations of heat transfer processes in the individual nodes multilayer walling» explores wall consisting of: masonry of silicate bricks, sand-lime brick cladding, insulation board «rockwool» and reinforced concrete slab. The study sites was derived problem area. It was the fact that the calculated temperatures were obtained below the dew point. Was upgraded to a given node. Solved the problem by adding an extra layer of insulation, then the calculated temperature returned to normal. The article carried the necessary thermal calculations walling, there are fields of temperature distribution, the quantity of heat flows by the grid method, the thickness of the investigated materials are selected. Calculation of multilayer enclosing structure was performed using the program Q-Basic. Under this program was made basic block diagram, which presents an algorithm for solving the problem. Solution of the problem of heat transfer is based on the integral – interpolation method, it is called – the method of elementary balances. Was also analyzed the results of calculations of transport processes in the building envelope using Fluent software and Elcut.
Keywords.Mathematical model, thermal physics, thermal conductivity, a program, node, function, design and construction.
