Endoscopic analysis of peristaltic propulsion of radiative hydromagnetic nanofluid with lubrication approach and slip constraints

Endoscopic treatment of gastrointestinal and respiratory diseases increases substantially in the current era, due to its minimally invasive nature. Advancement of endoscopic instruments is also the main factor in this field that facilitate the safe and healthy treatment. Nanomaterials are more effective to enhance the recovery process of the patients. Therefore, nanomaterials are used in the drug delivery procedures. External magnetic field devices are also used for numerous endoscopic treatments. Usually, magnetic field is used in the treatments, especially compression, anchoring, and guiding nanomaterial, and gives better results that are previously difficult. Heat is also produced in these procedures; therefore, Ohmic heating and viscous dissipation effect are studied. The role of thermal radiation to maintain the cooling process is also discussed in detail. Mathematical model is designed in the presence of these effects. Walls of the gastrointestinal tract are lubricated; therefore, slip constraints are also applied. Lubrication approach is used to simplify the system of equations. The resulting nonlinear system of equations and boundary constraints are solved via the numerical-differential Solve technique with the help of Mathematica software. Numerical analysis is performed to discuss the temperature, flow pattern and pressure gradient at the wall. In this article, we studied the endoscopic applications of magneto nanomaterials for the treatment of gastrointestinal and respiratory diseases such as cancer, stopping the bleeding due to ulcer, motility disorder and congenital. The results indicate that copper nanomaterials are more efficient to control the temperature and enhance the efficiency of the drug delivery process. Further role of magnetic field is prominent to control the flow phenomena of nanofluid.
