Influence of the geometry, relative position and length of sewer plate heat exchangers on their effectiveness

Anotacija

The effect of various dimensions of the shape, relative position and length of channels of plate heat exchangers on the effectiveness of the processes of hydrodynamics and heat transfer are analyzed. Based on the general theory of representations of the boundary layer, it is shown that the length of the entrance section of the hydrodynamic stabilization of flow while creating new and more efficient designs of plate heat exchangers should be accounted for. On the basis of the proposed hypothesis about the qualitative hydrodynamic analogy between the flow streams in plate and mixing heat exchangers, the effect of the relative position of the neighboring channels of plates on the hydrodynamics and the efficiency of heat transfer in a plate heat exchanger is shown. Keywords: plate heat exchangers, heat exchangers, mixing, geometry of channels, the input section of hydrodynamic stabilization of flow, the efficiency of heat transfer, aerodynamics, surface area, angle of attack
