Researchers at TU Wien have developed numerical models to simulate the movement of fluids in porous materials.

Within our solar system Earth is the only planet that has both plate tectonics and water. These may not be intuitively linked, as the amount of water is extremely small (a few hundred μg g −1) ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

A study on predicting acid-gas densities for the pressure and temperature ranges relevant to acid-gas injection schemes found that only one common equation of state gave unsatisfactory results.
