Sang W. Joong about the most profound change. This would have been so, even had the emergence of proto-democratic and democratic ideas at the end of the eighteenth century not magnified the importance of the Catholics. Even in its beginnings, the Catholic agitation produced remarkable effects. In the Catholic

Structure and stability of void waves in bubbly flowss into a kind of agitated, ‘turbulent’ bubbly flow. This turbulent flow is characterized by large collections of bubbles that violently move about in a kind of zig-zag motion. A further increase in the gas flux moves the point of transition downwards. An increase in the gas flux raises the gas volum

Surface Oscillations of Mutually-Interacting Gas Bubbles in a Sound Field in order to clarify the fundamental nature of the cavitation noise, many numerical simulations were performed for the oscillations of bubbles. However, numerical models used before were virtually restricted to the single bubble case . Since thousands of tiny bubbles are oscillating and moving

Pressure Waves in Bubbly Liquidshe combination of gas bubbles as the disperse phase and a liquid as the matrix, plays a special role in nature and practical applications and, consequently, has attracted researchers since many years. Even if such a bubbly liquid may exist only for volume (void) fractions of less than a few percent,

Structure of Shock Waves in a Liquid Containing Gas Bubblesime evolution of the shock wave is measured using two vertical glass shock tubes with different diameters, 18 mm and 52 mm. In the numerical simulation, thermal processes inside each bubble are directly calculated by using full equations for mass, momentum and energy conservation, and the results ar

High Frequency Nonlinear Waves in Bubbly Liquidnd for the sound speeds at zero and infinite frequency (equilibrium and frozen sound speeds), respectively. Also let Γ stand for an effective adiabatic exponent in a local approximation ... = (ρ/ρ.). for the equation of state in pure water (Γ ≈ 7). Then (cf Crighton 1991 for a simple derivation) the
