This research delves deeply into the intricate dynamics of the Soret effect within an unstable magnetohydrodynamic (MHD) mixed oscillatory flow occurring in a two-phase channel. The investigation spans a comprehensive spectrum of influences, including thermal, electrical, and chemical aspects. A pivotal aspect of this study involves the transformation of the governing equations into a dimensionless system, allowing for a nuanced examination of various media types, temperatures, and humidity levels within the specified research parameters. Subsequently, a rigorous analysis is conducted by applying the perturbation method to solve the equations. Through the utilization of illustrative charts, this study facilitates the computation of essential variables such as density and temperature. Furthermore, it delves into key parameters such as Gr, Gc, Sc, Sr, and others that characterize the flowing water.
