Liquefied Petroleum Gases [LPG] are flammable mixtures of gases such as propane and butane mainly which is transported stored in liquid phase storage vessels under amply pressure. These industrial processes high fire explosion hazard. When a vessel carrying LPG damaged, an abrupt drop pressure may release colossal quantities evaporating gas energy that has destructive effect on the itself its s...

During a study of reciprocating refrigerator compressor noise, it was desired to develop a new technique for visualizing of the vibrations of the shell surface. Previous investigators have shown the value of acoustical holography for this purpose in other applications. However, the spherical geometry of the compressor of interest required the use holography in spherical coordinates. The present...

Buoyant unstable behavior in initially spherical lean hydrogen-air premixed flames within a center-ignited combustion vessel have been studied experimentally under a wide range of pressures (including reduced, normal, and elevated pressures). The experimental observations show that the flame front of lean hydrogen-air premixed flames will not give rise to the phenomenon of cellular instability ...

Packed bed reactors have many applications in different industries such as chemical, petrochemical, and refinery industries. In this work, the effects of some parameters such as the shape and size of particles, bed size, and bed length on the hydrodynamics of the packed beds containing three spherical, cylindrical, and cubic particles types are investigated using CFD. The effect of the combinat...

Catamaran added V-like center bow (INCAT) is investigated as a wave-piercing vessel to decrease vertical acceleration and diminish slam events during sea-keeping operation. The catamaran and the vessel bow were modeled and the vertical acceleration of model was validated with experimenal test. The geometry of V-like center-bow such as slope of center bow and elevation from demi-hulls was optimi...
