Chemical reaction and viscous dissipation effect on MHD oscillatory blood flow in tapered asymmetric channel

MHD viscous oscillating type blood flow through lumen in arteries and varicose veins motivating to the study of disordered vessels veins. The nervous system, like other micro respiratory system is modeled geometrically shape tapered curvy walls varying cross section which new approach this problem same has advantage compared geometrical channel shapes. Blood taken as viscoelastic optically thick fluid flowing porous structure. Magnetic force considered normal direction system. Viscous dissipation chemical reaction effects on are analyzed.
