Experimental data on density (ρ) and speed of sound (u) at (303.15, 308.15, and 308.15) K are presented for the binary mixtures of (thiolane-1,1-dioxide + butanone), (thiolane-1,1-dioxide + pentan-2-one), (thiolane-1,1-dioxide + pentan-3-one), and (thiolane-1,1-dioxide + 4-methyl-pentan-2-one). From this data, excess molar volume and deviation in isentropic compressibility have been calculated. The Redlich−Kister polynomial equation was fitted to the experimental data.

This numerical work deals with the problem of Magnetohydrodynamics (MHD) flow of a doubly stratified Buongiorno’s nanofluid along a permeable vertical flat plate. The resultant dimensionless system of coupled non-linear differential equations is solved numerically by utilizing Pseudo Spectral Collocation Method with Local Linearization Technique. For diverse values of the flow influenced parameters, the fluid flow, heat and mass transfer characteristics are explored and shown graphically. The presence of both parameters strongly influences the convective heat and mass transport in the nanofluid medium.
