Анализ влияния реберной структуры на интенсификацию теплообмена в замкнутом кубе

Abstract

The objective of this research is to study the effect of solid fins on heat transfer enhancement in a cubical cavity. The number of solid fins varies from 1 to 3 and their lengths vary from 0,1L to 0,5L. A wide range of Rayleigh number and solid fins material has been investigated (10{3}<Ra<10{6} copper, aluminum and steel fins). The left vertical side where the fins are located is uniformly heated while the opposite side is kept at lower temperature. Other sides are considered to be insulated. Governing equations are solved using finite difference method. It is shown that having solid fins attached to the heated vertical side of the cubical cavity can lead to the heat transfer enhancement compared with a cubical enclosure without any fins and thus solid fins have a positive effect on heat transfer enhancement within the differentially-heated cubical cavity.
