Dual fractional analysis of blood alcohol model via non-integer order derivatives

Abstract

The concentration of alcohol in blood differs with vessel diameter (arterial diameter). In case of arteries having thinner diameter, alcohol concentrates around their walls because of Fahraeus–Lindqvist effect. The fluctuating concentration of alcohol in blood directly affects normal human body functions causing peptic ulcer and hypertension. In this work, we made the comparative analysis of blood alcohol model via Caputo–Fabrizio and Atangana–Baleanu fractional derivatives. The governing ordinary differential equations of blood alcohol model have been converted in terms of non-integers order derivatives. The analytic calculations of the concentrations of alcohol in stomach (C 1 (t) ) and the concentrations of alcohol in the blood (C 2 (t) ) have been investigated by applying Laplace transform method. The general solutions of the concentrations of alcohol in stomach (C 1 (t) ) and the concentrations of alcohol in the blood (C 2 (t) ) are expressed in the terms of wright function Φ(a, b; c). The graphs of both types of concentrations are depicted on the basis of fractional parameters of Caputo–Fabrizio and Atangana–Baleanu fractional derivatives. Finally, the comparative analysis of both fractional types of concentration of alcohol level in blood decay faster for higher fractional order.
