Determination of analytical dependences in order to calculate the exhaust gas boiler with helical belt inserts

The objective of the research is the identification of regularities of heat and aerodynamic processes and determination of analytical dependences in order to calculate heat exchange Nu = (Re, S/d) and aerodynamic resistance = f(Re, S/d) of the exhaust gas boiler with helical belt inserts. The experimental research of heat exchange and aerodynamics of all used helical belt inserts was performed in the same conditions, based on one methodology and the same ex-perimental installation. The received dependences help to evaluate the increasein heat exchange and aerodynamic resistance of a gas flow while using helical belt inserts with different geometrical specifications, and to select the best option of the geometry of the insert for a specific construction of a recuperative heat exchanger with multi-phase heat exchange environments.
