This study analyzes the behavior of a differentially heated channel flow by means direct numerical simulations (DNS) with variable thermophysical properties under low-speed conditions focusing on impact temperature gradient turbulence structures near walls. The were conducted at mean friction Reynolds number Re{\tau}m = 400 ratio between walls Thot/Tcold 2. Results show significant differences hot and cold that lead to an increased heat transfer wall higher turbulent production in wall.
Abstract The space industry is growing and data are becoming accessible to businesses that were previously unthinkable. Constellations of small satellites in Very Low Earth Orbit (VLEO) have created a gap allowing medium-sized companies gain momentum by developing new strategies technologies. According Euroconsult forecasting, the NewSpace market will grow from $12.6 billion $42.8 next decade (2019–2028). Despite study’s limitations uncertainties satellite market, results obtained this...
A direct numerical simulation (DNS) of an asymmetrically heated turbulent channel flow has been performed to study the temperature gradient effects on turbulence. The case set as a compressible with variable thermophisical properties at mean friction Reynolds number Reτm = 400 submitted hightemperature between two walls (Thot/Tcold 2). behaviour differences are discussed.
