    In determining the fluid saturations from a core sample, two techniques are commonly employed; evaporation of the fluids in the pore space, known as the retort method, and the leaching of fluids in the pore space, known as the dean-stark extraction method. particle level set method and a coupled level set and volume-of-fluid method, have been implemented with the aim at improving the mass conservation property of the level set method.

    The volume of fluid is an interface tracking method used for multiphase flow. the the interface between gasoline and air is tracked by a color function and the interface is displace fluid - this method can be used to calculate the volume of gas. the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction. use a spirometer - it measures the volume of air coming into and вђ¦
