The double-diffusive natural convection in an enclosure filled with nanofluid is studied using ISPH method.The model used for the nanofluid incorporates the effects of catherine lansfield ombre rainbow clouds eyelet curtains Brownian motion and thermophoresis.In addition the thermal energy equations include regular diffusion and cross-diffusion terms.In ISPH algorithm, a semi implicit velocity correction procedure is utilized and the pressure is implicitly evaluated by solving pressure Poisson equation.The results are presented with flow configurations, isotherms, concentration and nanoparticle volume fraction contours and average Nusselt and Sherwood numbers for different cases.

The results from this investigation are well validated and have favorable comparisons with previously published results.It is found that, among all cases, a good natural convection can be obtained by considering the double diffusive case.An increase in Soret number accompanied by a decrease in Dufour number results 7gm pravana in an increase in average Nusselt number and a decrease in average Sherwood number.
