在不同热流值下，研究了由9个加热圆柱组组成的单个加热圆柱体和3个加热圆柱体在水中的自然对流换热。用节径比为2的三列方形节距组装成三个细长圆柱体，得到了总Nusselt数与平均修正Rayleigh数的经验关联式，并与文献中的关联式进行了比较。
Natural convection heat transfer from a single heated cylinder and three heated cylinders in an assembly of nine cylinders immersed in water is investigated at different heat flux values. The thin cylinders are assembled in three by three array of square pitch having a pitch to diameter ratio of 2. Empirical correlations for the overall Nusselt number versus average modified Rayleigh number are obtained and compared to the literature’s correlations.
