Fuel Cells

What are Fuel Cells? Fuel cells are devices that directly convert chemical energy to electricity through electrochemical reactions. Although there is a resemblance between fuel cells and batteries, their specific characteristics make them widely used in industries and be under…

Y-Plus Application in CFD Simulation

Introduction The dimensionless variable Y-plus represents the distance from the wall to the first grid cell's center, also, Y-plus is a distance with no dimensions. In other words, Y-plus renders the vertical space between the element's center and the wall…
