Development of optimization method for plate heat exchanger with undulation

Original language description

The article deals with optimization of undulated heat transfer surface of plate heat exchanger. Thegoal of optimization is not only to increase effectiveness of heat transfer but also to reduce the pressure drop. Acombined pattern of undulation which combines herringbone pattern and wavy pattern was optimized and bestvalues of four parameters were found; angle of herringbone pattern, number, phase and amplitude oflongitudinal waves of wavy pattern. The optimization procedure looked for maximum of objective functionwhich was a linear combination of effectiveness and pressure drop. We used simple Monte Carlo method andthe optimum was searched for four values of reference pressure drop. Four different optimization were run andwe investigated the effect of various definition of objective function and parameters of undulation. It wasfound that during optimization of combined pattern, the herringbone pattern is more favoured than wavypattern. It is caused by the fact that herringbone pattern was described by the only one free parameter, whichwas the angle of undulation, and therefore it is more likely to be found by a stochastic method. Thisassumption was confirmed when simple wavy pattern was optimized and higher values of objective functionand effectiveness were found.
