Analytical Calculation of Systems of Regulation Counterflow Heat Exchanger Devices


V.M. Artyushenko, S. Yu. ChekmaevL. A. Prokudina, E. A. Salamatov

Effect of shear stress on evolution of disturbances on liquid film is investigated. Instability areas in co- and countercurrent modes are calculated for Re[1; 10]. At finite-mode approximation five waves amplitudes are calculated for optimal modes of liquid film flow.Process of introduction of system of automatic control in work counterflow heat exchanger device is considered; the PI – and PID-REGULATORS calculation is made for work with the given device; formulas for calculation of options of typical systems of regulation of counterflow heat exchangers are resulted.
