The present study is devoted to analyze the influence of thermal radiation and chemical reaction on a transient incompressible natural convective flow of nanoliquid saturated porous medium through two rigid, parallel asymmetric plates with the negligible thickness and capable to transfer the heat with nano-liquid by convection. It is assumed that nano-liquids are made up with pouring various types of nanoparticles into the water based fluid. Single phase model is adopted to determine the thermo-physical properties of the nano-liquid and simple Darcy model is utilized to predict the flow through porous medium. The transport equations are solved to analyze the important characteristics of momentum, energy and concentration by Differential Transform Method. To compare these semi-analytical results, Crank-Nicolson finite difference scheme is used and it was in good agreement. The study reveals that Biot number influences appreciably on the velocity, temperature and concentration distributions. The significant variation in the concentration profile is found by imposing chemical reaction in the case of large Biot number.
