摘要：

Various engineering systems, such as those associated with crystal growth techniques or solar ponds, may be characterized by double-diffusive behavior induced by discrete heat sources. Due to the relevance of such systems, the objective of this study is to investigate double-diffusive convection induced by bottom heating with a finite, heated strip placed beneath a salt-stratified layer. Attention is focused on the formation and growth of convecting regions in the salt-stratified fluid . Experimental and numerical results reveal that development of convective conditions is characterized by an interaction betwen Rayleigh-Benard-type convection and longitudinal convective rolls formed by horizontal temperature gradients.
