HEAT TRANSFER IN THE FLOW CHANNEL IN TUBE BUNDLE CORRIDOR TYPE UNDER IMPOSED ON THE FLOW LIQUID OF UPSTREAM LOW-FREQUENCY ASYMMETRICAL PULSATIONS

Velocity profiles in the heat exchanger for water stream low-frequency asymmetrical with upstream pulsations (LFAUP) were obtained experimentally. Mathematical model for heat transfer modeling with LFAUP in the corridor tube bundle was developed. According to the results of numerical and physical ex...

description Velocity profiles in the heat exchanger for water stream low-frequency asymmetrical with upstream pulsations (LFAUP) were obtained experimentally. Mathematical model for heat transfer modeling with LFAUP in the corridor tube bundle was developed. According to the results of numerical and physical experiments the correlation for the Nusselt number (Nu) with LFAUP for the ranges of Reynolds number 100< Re < 1000, Strouhal number Проблемы энергетики, 2016, № 11-12 0,026 < PSh < 2,6 and 2,6 < Re(pSh) < 260 was obtained. Nondimensional amplitude was 1,25 < p < 4,5.
