As one of the commonly used blackbody types for infrared radiation calibration, emissivity level surface is limited by coating and microstructure array. To study coatings influence on blackbodies, we establish optical mechanical models four different array concave cavity including triangular cavity, quadrangular pentagonal hexagonal arrays. Based Monte Carlo ray tracing method, simulation calculations are carried out, with a focus analyzing effects structure type, properties coatings, height...
Abstract The spaceborne blackbody with high emissivity can provide accurate infrared radiation to calibrate payloads. To meet the need for improving accuracy of value traceability, this paper investigates mechanism enhancing through structure cavity. directional calculation based on Monte Carlo optical simulation was carried out. normal and distributions cylindrical cavity trap-cavity (TCB) were simulated compared. 8–14 μm band measured. experimental results indicate that TCBs demonstrate...
On the basis of adjustment plan whole reservoir, 272 wells are drilled in Shengli Chengdao offshore oilfield. The new production capacity is bout 2.05 million tons per year. existing problems pointed out according to adaptability analysis oil-gas gathering and transforming networks before after reservoir old areas account exiting pressure drop simulation pipe networks, EF model selected which can be used simulate In meantime, influence service life on flow efficiency effect oil viscosity...
