Abstract. The paper presents a mathematical model for the calculation
of resistance to heat transmission at the cross-flow of gas. The obtained
mathematical expressions show that the resistance to heat transfer at the
cross-flow of gas is determined by the following influential values: the
method of setting processed elements, the setting height, the available
cross passages, elements density, the heating/cooling rate and the characteristic
temperature in the voids existing between set elements.
MATEMATIČKI MODEL ZA PRORAČUN OTPORA PRENOSU
TOPLOTE POPREČNIM
STRUJANJEM GASA U TUNELSKIM PEĆIMA ZA PROIZVODNJU
GRAĐEVINSKE KERAMIKE
U radu je prikazan matematički model za proračun otpora prenosu toplote
poprečnim strujanjem gasa. Dobijeni matematički izrazi pokazuju da je otpor
prenosu toplote poprečnim strujanjem gasa određen sledećim uticajnim veličinama:
načinom slaganja i geometrijom sloga, visinom sloga, učešćem poprečnih
pasaža, gustinom elemenata, brzinom zagrevanja odnosno hlađenja i karakterističnom
temperaturom u međuprostoru rešetke sloga.
