WebFeb 23, 2024 · A gradient is simply a change in the amount of something. For example, you may have seen a color gradient (like the one shown at the right), where you start with a single color that slowly fades to white. In this case, the color is what is changing, so we call it a “color gradient.” WebDensity gradient arises from temperature difference between the heated wall and the coolant air. Abdelmeguid and Spalding (1979), Cotton and Jackson (1987) found that the centrifugal buoyancy force enhances the turbulent energy for outward flow.
