Abstract The present study examines the thermal characteristics and stresses at boundary for peristaltic motion of Reiner‐Philippoff fluid through a symmetric channel. (R‐P) model is widely recognized its ability to provide comprehensive representation unique properties exhibited by non‐Newtonian fluids. One notable aspect that initiates this nonlinear relationship between velocity gradient shear stress. Moreover, captures implicit connection deformation rate Additionally, R‐P exhibits distinct characteristics, acting as dilatant , exhibiting pseudoplastic behavior behaving Newtonian when . Governing equations are mathematically modeled under consideration mixed convection, viscous dissipation, magnetic field, Joule heating effects. Long wavelength small Reynolds number approximations used simplify system. To compute numerical solution simplified system, BVP4c technique employed via MATLAB. influences key parameters on flow physically visualized graphs. A detailed analysis heat transfer dilatant, pseudoplastic, fluids also provided. assessments wall presented tables. Outcomes reveal temperature profile decreases due parameter Bingham number. findings case indicate both enhanced Grashof Hartmann numbers lead an increase in profile. Tabular results improved developing values Brinkman numbers, while exhibit opposite behavior. decrease with greater Furthermore, more effective improving reducing compared

Endoscopic treatment of gastrointestinal and respiratory diseases increases substantially in the current era, due to its minimally invasive nature. Advancement endoscopic instruments is also main factor this field that facilitate safe healthy treatment. Nanomaterials are more effective enhance recovery process patients. Therefore, nanomaterials used drug delivery procedures. External magnetic devices for numerous treatments. Usually, treatments, especially compression, anchoring, guiding nanomaterial, gives better results previously difficult. Heat produced these procedures; therefore, Ohmic heating viscous dissipation effect studied. The role thermal radiation maintain cooling discussed detail. Mathematical model designed presence effects. Walls tract lubricated; slip constraints applied.

Abstract Endoscope is a very important tool for medical diagnosis and they have many clinical applications. The endoscope now used determining real reasons responsible problems in the human organs which fluid transported by peristaltic pumping such as stomach, small intestine, etc Therefore, this paper discusses influence of an on flow Jeffery annulus considering entropy generation. inner tube uniform rigid fulfilled slip conditions, while outer having sinusoidal wall has no-slip condition. impacts thermal radiation viscous dissipation are also considered energy equation. analysis been developed low Reynolds number long wavelength approximation. analytical solution velocity, pressure gradient, temperature, streamlines, generation, Bejan obtained using perturbation method, then results plotted to see different physical parameters. major outcomes disclosed that velocity profile decreases near region due parameter radius. However, it increases amplitude ratio. temperature distribution rises with Brinkman number. On other hand, declined parameter. Furthermore, generation number, but present study application endoscopes, diagnose internal organs. Also, variation gradient helps maintain rate essential during insertion catheter into artery.
