Drag modeling

Similar comments could be made for a detailed model of drag. It is not unusual to have a large table of drag vs Mach number for high performance aircraft. Regardless of how the data is presented, once the thrust available and thrust required (drag) curves are plotted we can determine the level-flight flight envelope as described above. Special Case - ….

The G7 drag model has proportionally more drag at transonic speed compared to the G1 drag curve, and by a significant margin. In fact, transonic speed is where drag models diverge the most. As a result of the divergence in drag models at transonic speed, ballistic solvers can calculate different transonic trajectories for G1 vs. G7 BC models.For this reason many studies on torque & drag modeling have been performed. In this regard different approaches have been used; the difference in these …

Mesoscale drag modeling is the critical issue for the simulation of gas–solid two-phase flows. This article reviews the physical origin of the drag force and the …Drag refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas). Drag forces act in a direction opposite to the oncoming flow velocity. This means that there will be some minus signs in upcoming equations. Drag forces depend on velocity.
