Liquid hydrogen has been studied for use in vehicles. However, during the charging process, liquid is lost as gas. Therefore, it necessary to estimate and reduce this loss simulate process. In study, initial process of a vehicle tank under room temperature atmospheric pressure conditions was numerically investigated. A transient thermal-fluid simulation with phase-change model performed analyze...

Large amounts of chlorine released in a few minutes from pressurized liquefied storage such as a railcar may form a dense two-phase (gas plus small liquid aerosol drops) cloud at ground level. The time duration of release from the storage tank could be as small as a few seconds for a large hole with diameter exceeding 20 or 30 cm. But even if the release from the tank occurs in a few seconds, a...

An analysis of the strati®cation decay in thermally strati®ed vertical cylindrical cool storage systems is presented using a one dimensional conjugate heat conduction model. The degree of thermal strati®cation depends upon the length to diameter ratio, wall thickness to length ratio, the thermo-physical properties of the material of the storage tank, the type and thickness of the insulation and...

An explosion occurred at a polyvinyl chloride (PVC) resin manufacturing plant. The explosion originated at an atmospheric storage vessel when it received a slurry discharge from a suspension polymerization reactor. The pressure rise caused by the uncontrolled flashing of superheated liquid vinyl chloride resulted in the complete separation of the roof from the tank shell. A cloud of vinyl chlor...

Common practice methods of tank design for transportation liquefied natural gas don’t take into account the specifics carriers operation under condition partial filling cryogenic tanks. A new method designing type-C is proposed. Method based on solving problem increasing volume transported by small-scale inland carriers. The usage a number limiting parameters: minimal allowable ventless time, v...
