This work examines the double diffusion of rotated Z‐shaped and sloshing fins inside a nanofluid‐porous cavity. The novelty of this research lies in its utilization of the ISPH method to handle the complex fluid‐structure interactions occurring at double diffusion within the nanofluid‐porous cavity. Two thermal/solutal conditions of the rotated Z shaped entitled C1 (), and C2 () are conducted in this work. The ISPH method solves the nonlinear systems of the fluid‐structure interactions during thermosolutal convection. The impacts of the inclined magnetic field and Soret–Dufour numbers are discussed. The Z shaped rotates circularly around its center and the four fins are sloshing on the boundaries. Natural convection is dominant because the rotation speed is slow, and the buoyancy force is strong. The obtained simulations revealed the changes in the isotherms, isoconcentration, and the nanofluid velocity under the variations of boundary conditions in Z shaped. It is seen that C1 always supports higher velocity, temperature, and concentration as well as mean Nusselt number ‐Sherwood number compared to C2. The Soret number plays a good role in the improvement of double diffusion and nanofluid velocity compared to the Dufour number which has fewer contributions.
