The hydraulic resistance in the small-scale pillow-plate heat exchangers
(Національний університет "Львівська політехніка", 2019) Arsenyeva, O. P.
The Pillow-Plate Heat Exchangers (PPHEs) are rated as innovative type of heat transfer equipment. The present paper gives the information about the research made in Paderborn University aimed to investigate the heat transfer and pressure drop in the channels of the small-scale PPHE.
The estimation of heat transfer area of pillow-plate heat exchangers for water heating
(NTU "KhPI", 2017) Arsenyeva, O. P.; Kapustenko, P. O.; Vasilenko, O. A.; Tran, J. M.; Kenig, E. Y.
Efficient heat recuperation is of primary importance in resolving the problem of efficient energy usage and consequent reduction of fuel consumption and greenhouse gas emissions. To solve this problem, different strategies can be used, but all the approaches need efficient heat transfer equipment. One of the innovative types of heat transfer equipment is the Pillow-Plate Heat Exchangers (PPHEs). The present paper gives the information about the main manufacturers of PPHEs, describes the existing approaches for determining the pressure drop and heat transfer. The application of the PPHE for water heating is considered, and the resulted heat transfer area is compared with the surface of chevron-type plate heat exchanger designed for the same process conditions.
