The thermal management of a system needs an accurate and efficient measurement exergy. For optimal performance, entropy should be minimized. This study explores the enhancement exchange in stream Eyring–Powell fluid comprising nanoparticles saturating vertical oriented dual cylindrical domain with uniform conductivity viscous dissipation effects. A symmetrical sine wave over walls is used to in...

The present investigation emphasises a new attempt at the peristaltic mechanism of Eyring Powell fluid through non-uniform channel. analysis is performed in presence wall properties under influence variable liquid properties, and flow problem mathematically developed. channel walls are subjected to no-slip conditions with long-wavelength low Reynolds-number approximations employed study. nonlin...

The current article has investigated unsteady convective flow for MHD non-Newtonian Powell-Eyring fluid embedded porous medium over inclined permeable stretching sheet. We have pondered the thermophoresis parameter, chemical reaction, variable thermal conductivity, Brownian motion, variable heat source and variable thermal radiation in temperature and concentration profiles. Using similar trans...

The idea that demographic change may spur or slow down technological change has become widely accepted among evolutionary archaeologists and anthropologists. Two models have been particularly influential in promoting this idea: a mathematical model by Joseph Henrich, developed to explain the Tasmanian loss of culture during the Holocene; and an agent-based adaptation thereof, devised by Powell ...
