Peristaltic transport of mixed convective two-phase nanofluid with Ohmic heating used in drug delivery systems: Adomian decomposition method

Flow through flexible wavy walls, the peristaltic transport has widespread applications in various sectors such as biomedical engineering, particularly in drug delivery systems, dialysis, etc., where the role of flexible conduits is crucial in controlling fluid flow. Peristaltic phenomena are utilized in several industrial processes like microfluidic devices. The proposed study focuses on the peristaltic flow of two-phase nanofluid within flexible wavy walls by including thermal radiation and Ohmic heating. The interaction of both the flow properties influences the temperature distributions and flow characteristics within the channel. The heat transfer rate increases due to the inclusion of the thermal radiation; however, Ohmic heating contributes a significant augmentation in the fluid temperature due to the electrical conducting nature of the fluid. A comparative analysis is presented using the Adomian decomposition method, as semi-analytical method. The behavior of several characterizing factors is presented briefly and described in the discussion section. However, the important findings are the buoyant forces accumulated with both thermal and solutal Grashof number that enhance the fluid velocity; however, a smooth retardation occurs at both the walls for the increase in inertial drag.
