Finite element analysis of effects of temperature on blood flow in human atherosclerotic radial artery under heat generation Available to Purchase

In this context, we will analyze temperature, velocity and pressure changes using a computer simulation based on finite element analysis of blood flow in the human atherosclerotic radial artery. The radial artery represents a potentially beneficial avenue for in vivo assessment of systemic atherosclerosis. Analysis of radial artery atherosclerosis is linked to numerous conventional cardiovascular risk factors and confers diagnostic and predictive insights into coronary artery disease (CAD). In this scenario, normal pressure is applied at the inlet and outlet. This alteration modifies the blood flow velocity, pressure, and bio-heat transfer. The numerical analysis employs three equations: the Navier-Stokes equations regulate the movement of blood by determining the velocity profile and pressure levels; the electric current equations are for generating heat and the heat equation calculates temperature changes, considering the boundary conditions along with the normal temperature of the artery. In this case, a time-dependent function is utilized, incorporating inlet velocities and outlet pressures to determine more realistic values for blood velocity and pressure. The numerical results reveal that temperature on the heat-affected side initially increases rapidly, reaches a maximum, and then gradually decreases before stabilizing indicating the localization of heat. The velocity of blood flow exhibits a pattern similar to the normal radial pulse propagation, but is lower before the plaque area compared to the later area of the plaque. This model could enhance our understanding of blood flow behavior in atherosclerosis and potentially lead us to consider the application of heat using microdevices controlled by AI.
