Popis:	Objectives: To investigate the effects of Magneto Hydro Dynamic marangoni convection in nanofluids subject to radiation along with first order chemical reaction. Method: The analysis is taken over Copper-Water and Silver-Water nanofluids. Water with Prandtl number 6.2 is taken as base fluid. Flow equations are formed by a suitable similarity transformation. Using MATLAB, numerical solutions are obtained for Velocity, Temperature and Concentration of the nanofluid particles for different parameters. Also it is observed the heat and mass transfer effects. Results: The effect of magnetic parameter on fluid motion and temperature is appreciable. Further at low magnetic number ( ), velocity of Cu nanofluid particles move faster than that of Ag nanofluid particles. It is observed that increase in Soret number results in decrease of mass transfer rate and this rate is more in Ag-water nanofluid. Conclusion: Copper nanofluid particles possess higher heat and mass transfer rates. It is also noticed that Sherwood number decreases with increase of Soret number.
