Abstract
The present invention discloses apparatuses, systems, and methods for controlling liquid impact pressure in liquid impact systems. The liquid impact systems include at least one gas and a liquid, the gas having a density (PG) and a polytropic index (κ) and the liquid having a density (PL). The methods include the step of calculating a liquid impact load of the liquid on the object by determining a parameter Ψ for the system, wherein Ψ is defined as (PG/PL) (κ−1)/κ. The systems are also configured to utilize the parameter Ψ. The parameter Ψ may be adjusted to increase or reduce the liquid impact load on the system. Automatic, computer-implemented systems and methods may be used or implemented. These methods and systems may be useful in applications such as LNG shipping and loading/off-loading, fuel tank operation, manufacturing processes, vehicles dynamics, and combustion processes, among others.
