In order to accurately know the temperature field around a fixed anchorage and the heat loss of buried pipe we used the numerical simulation technology to simulate the temperature field in fixed anchorage of buried heating pipes, then, we got the intuitive temperature distribution figure and the size of heat loss. The simulation results indicate the necessity of effective insulation measures for fixed...
The large-diameter flat serpentine finned tube is often used in direct air-cooled condensers. The distribution of the air velocities and the temperatures in the serpentine finned tube were analyzed by using three-dimensional numerical simulation methods. The heat transfer coefficients in finned tubes were obtained, which were subsequently used to fit the relational formulas of the heat transfer coefficients...
The article researches the performance of the diesel engine adopting variable composition air using numerical simulation and experimental methods. The mechanism of NO formation has been validated. At the same time the experiment and numerical simulation show that it is useful to lessen the diesel NO emission owing to adopting NEA (nitrogen-enriched air) technology and nitrogen concentration need not...
In this paper a type of ultra supercritical boiler was researched for BMCR operating condition numerical simulation with the CFD software Fluent. When this type of boiler burning design coal in the BMCR operating condition, the combustibles content of fly ash is low, the combustion efficiency is high and the emission of NOx is low. The maximum heat load of the wall is located between the burner and...
