Add to ORKGThe master’s thesis is focused on the calculation of a heat exchanger with a crossflowed tube bundle found most in the air-cooled heat exchangers. The knowledge gained from the literature search is used to create libraries, giving a choice of several different methods in the hydraulic and thermal calculation as well as other key areas. These libraries allow their implementation in the comprehensive computational software P.E.C. developed at the Institute of Process Engineering. The thesis includes a verification of the correctness of the library’s calculations with showcased problems as well as 2 parametric studies. These investigate the dependencies of the transverse and longitudinal pitch on some of the process parameters of the heat exch...
