Set Up

The flow of liquefied natural gas (LNG) which was coupled between heat transfer and fluid-flow in rib-tube was studied in this paper. Based on theoretical analysis, the model and wall-function were chosen to simulate the flow field of rib-tube, and the multiphase flow was described by the mixture model, in which the dispersed phase was defined by different velocity. In addtion, self-defining functions were used and governing equations were set up to solve the dispersed phase, and the result were compared with the experiment. The process of fluid-flow and heat exchange on rib-tube was simulated, and the contours of temperature, pressure, velocity, gas fraction were obtained, which showed that, the parameters of above changed when the temperature was rising and the LNG evaporating along the rib-tube, and a mixed process existed in the middle of the heat tube.

Simulation And Experiment

The numerical simulation and experiment method for temperature field research in the laser quenching process is proposed. First, several assumptions of the laser quenching process are discussed for the research convenience. The simulation process is analyzed by the Laser Heat-Treatment-2 software, which is developed in FORTRAN. A discrete simulation process and results are given through the setting of different parameters in the laser quenching process. Finally, the experimental study is carried out to demonstrate the validity of the simulation results.

Submerged Combustion

The submerged combustion vaporizer (SCV) is a kind of equipment used for liquefied natural gas (LNG) vaporization. In order to get insights into the heat transfer of supercritical LNG, numerical simulations were carried out in this paper for investigating heat transfer of LNG in horizontal circular tubes under supercritical pressure. Numerical results showed that LNG temperature at the outlet under the design parameters was 276 K which met the demands of application. The velocity of LNG at the outlet was 12 m/s, and the pressure drop along the ducts was 120 kPa.

Liquefied natural gas (LNG) is obtained by reducing the gas temperature to-162 degree, Fault of the inside steel cans, the insulation layer or the concrete outer tank of the LNG storage tank can lead to changes of the temperature field, local temperature decreases, and the outer concrete tank safety is threatened. Infrared thermal imagers are used to monitor the temperature of the LNG storage tank, get the overall temperature distribution image of the outside concrete tank, establish the communication between the thermal imagers and the computer, and analyze the heat image of tank by the compute, find out the failure structure of the LNG storage tank according to the temperature field changes. Multi-point temperature monitoring system for the LNG storage tank can provide powerful guarantee for the safe storage of the liquefied natural gas.

The Impact

The effect of the air inlet and the air outlet of the strawberry greenhouse are very significant to the microclimate in greenhouse under the conditions of natural ventilation. This paper studied the numerical simulation and experiment of indoor temperature field of the strawberry greenhouse with natural ventilation in different areas of air inlet and air outlet. The impact of the natural ventilation on the microclimate of strawberry greenhouse has been explored. The results indicated that the air velocity and temperature in the air inlet effected on the temperature distribution within the greenhouse, and the temperature near the air inlet was susceptible to the outdoor environmental parameters. The general trend of the variation of the indoor temperature in the greenhouse decreased with increasing the sizes of the air inlet and the air outlet. The overall trend of temperature gradient is similar within the greenhouse.
