Example 1. A Terminal Velocity Find the terminal velocity of an 85-kg skydiver falling in a spread-eagle position. Strategy At terminal velocity, Fnet = 0. Thus the drag force on the skydiver must equal the force of gravity (the person’s weight). Using the equation of drag force, we...
Skin friction of a fluid flowing near a solid surface induces many problems in daily life and industrial processes (Leschziner, 2020; Liu et al., 2020; Ricco et al., 2021). For example, friction significantly influences on the transportation efficiency of both water and oil in pipelines (Avk...
Description of the preceding is easiest by example and some follow. No attempt is made to illustrate the engineering breadth of problems handled by these methods over the last century or so. If we suspect that the behavior of a system might be influenced by several variables (x′s), this ...
d. To force or bring out with great effort: dragged the truth out of the reluctant witness. 5. To mention or introduce (an unpleasant or tedious subject): dragged up that embarrassing incident; is always dragging his money problems into the conversation. 6. a. To search or sweep the bo...
The only one that the error does not exist is with the 3840x2160 screen. I have tried to force the error and have not succeeded. With the other two screens I have tried connecting 1 single monitor, 2 monitors, changing the order of the screens in windows and the error keeps occurring....
i am a new user in openFoam ,I want to know why it do not use the U and p in caculating the forces and forcecoeffs? And i also want to know why it always has the error :From function void forces::read(const dictionary& dict) ...
What is the expected behavior? Drag and drop working :) What is the current behavior? If I change the height of elements (that are draggable) for example by hiding some elementsafter I start dragging, the drag and drop mechanism thinks the items are still the original height (and therefore...
The drag force on the plate has been meas- ured as a function of the plate velocity in steady state and in relaxation after stopping the movement. The role of the initial stress state in the fluid was highlighted. Secondly, numerical simulations were carried out using the finite element ...
After finding out the drag coefficient, the drag force acting on the body can be found using Eq. (60). One should understand that the drag coefficient is significantly affected if another body with free stream turbulence and disturbance is also present. For example, flow over tube bundles and...
Meanwhile, drag-along rights favor majority shareholders.3When a majority shareholder decides to sell their shares, they can exercise drag-along rights to force the minority shareholders to also sell their shares to the same buyer. This is a way to ensure the majority shareholder can deliver 100...
