Rayleigh‐Benard convection in a dielectric liquid: time‐periodic body force

We discuss the thermal instability in a layer of dielectric fluid when the boundaries of the layer are subjected to small amplitude Time‐periodic body force (TBF). Perturbation solution in powers of the amplitude of the applied temperature field is obtained using the Venezian method (1969) [1]. A linear stability analysis is performed. The results of the study, indicate that TBF or g‐jitter leads to delayed convection Also for large frequencies the effect of TBF disappears.The problem has relevance in many dielectric fluid applications wherein regulation of thermal convection is called for.
