Original abstract
This paper presents a developed mathematical model of one-dimensional steady single-phase fluid flow in a parallel system of an economizer for high-pressure (10 MPa) water preheating. Preliminary design of the flow system from the technical-economic point of view is used as a basis for geometry optimization ensuring as low a fluid distribution non-uniformity as possible. The model is utilized for prediction of fluid distribution, outlet temperature and pressure drop on tube side with regard to a known range of operating conditions. It can be used for both incompressible and compressible fluids. Due to the structure of the serpentine coil, a non-uniform heat flux density along the length of individual tubes as well as their different lengths are taken into account.
