Abstract. In this paper, an iterative procedure for thermo-hydraulic
calculation of shell and tube heat exchangers according to prescribed pressure
drop, has been presented. From this procedure it is possible to predict
the heat exchanger geometries for which one can expect in advance to satisfy
the thermo-hydraulic conditions of project. It remains to the designer
to pay a full attention to the analysis of possible solutions and to the
choice of optimal heat exchanger geometry.
Key words: shell and tube heat exchanger, design, iterative

NOVI POSTUPAK ZA PRORAČUN I PROJEKTOVANJE
DOBOŠASTIH IZMENJIVAČA TOPLOTE
U radu je prikazan jedan iterativni postupak za termo-hidraulički proračun
dobošastih izmenjivača toplote prema pripisanom padu pritiska. Ovim postupkom
moguće je predvideti set geometrija izmenjivača toplote za koje se unapred
može očekivati da će zadovoljiti termo-hidrauličke uslove projekta. Na
ovaj način projektanti punu pažnju posvećuju analizi mogu}ih rešenja i
izboru optimalne geometrije izmenjivača toplote.
Ključne reči: dobošasti izmenjivač toplote, proračun, iterativni
