摘要

The conjugate heat/mass transfer from a circular cylinder in laminar crossflow was analysed in [1,2]. Unfortunately, due to an error occurred during data processing, the figures that present in [1,2] the local Nu number are wrong.rnFig. 1 of the present note shows the accurate values of the local Nu number for the case analysed in [1]. Thermal wake exists only in the region of the rear stagnation point (θ = 0). For flow without separation (Re = 2 - Fig. la), the evolution of the thermal wake phenomenon is similar to that observed for spheres in creeping flow. For flow with separation (Re = 20 - Fig. lb) thermal wake occurs in the vicinity of the flow separation point. Thus, the discussions from [1] about the thermal wake phenomenon and the last column of Table 5 should be ignored. All the other results presented in [1], i.e. asymptotic values of the average Nu values (overall and fractional), time variation of the cylinder average temperature, the influence of kinetic and thermodynamic ratios on conjugate transfer, remain valid.
