| 内容記述 | Numerical investigations are made of convective heat transfer of an incompressible fluid in a sidewall-heated cavity which is exposed to periodic external excitations. Three types of time-varying environments are considered; vertical and horizontal g-jitters, and temporal oscillation of the hot sidewall temperature. Comprehensive numerical solutions to the Navier-Stokes equations are acquired with varying the amplitude and frequency of external forcing. The time-dependent heat transfer characteristics of the interior fluid are analyzed to illustrate the presence of esonance, which is characterized by maximal amplification of the fluctuations of heat transfer. The numerical results disclose that the basic mechanism of resonance for any external excitations is essentially similar. The flow is shown to resonate with internal gravity wave oscillations. The independent effects of the kind of external forcing and the principal parameters on the resonant convection are scrutinized. The possibility of heat transfer enhancement by use of resonance phenomenon is suggested. | |||||||||
