The discrete element method and simulation analysis of the interaction between granular materials implements provide a convenient effective for optimal design farming machinery. However, parameter differences different make impossible to carry out directly. It is necessary obtain specific material parameters contact through calibration object, so as results more reliable. Parameter mainly inclu...

hot-wire spirometer uses a constant temperature anemometer (cta) for its operation. the working principle of cta, used for the measurement of fluid velocity and flow turbulence, is based on convective heat transfer from a hot-wire sensor to a fluid being measured. the calibration curve of a cta is nonlinear and cannot be easily extrapolated beyond its calibration range. therefore, a method for ...
