Effect of radiation, temperature dependent heat source/sink, concentration dependent mass source are taken into account. To tackle the highly complex nonlinear problem, the perturbation technique is applied with long wave approximation.en-USHeat transferconvective flowwavy channelmass transfertravelling thermal wavesArticle
