standard wind
6.ε model etc. provided by professional computational fluid dynamics software Fluent 6, the 3D steady wind flow field around standard low-rise building TTU in atmospheric boundary layer is numerically simulated. The results of numerical simulation are compared with TTU field measured data and Tongji University TJ-2 wind tunnel test data.
7.In different wind-tunnel conditions, the drift using a low-volume standard fan nozzle Lechler 110015 was much more than that of Lechler 11003, which is a high-volume nozzle.
8.It is pointed out that the damage from wind waves to a dam and the rise of the mean water level and wave runup caused by wave breaking on the sloping beach of dams is the main factor threatened the safety of the dam, and the action of wlnd waves decreases both the capacity of storing water and the standard of prevention of flood in reserviors.
9.In 1995 fuel-saving stoves, methane, solar, wind and geothermal energy sources and small hydropower stations began to develop and were popularized in rural areas throughout the country. In this way, annually 80 million tons of standard coal equivalent can be saved and additionally produced. Methane-generating pits for agricultural use were dug to benefit 5.69 million households and fuel-saving stoves were in use in 170 million households.
