The feasibility of using microfinned microchannel structures in copper heat exchangers designed for cooling semiconductor
modules that pump powerful solid-state lasers is considered. Efficient heat exchangers are developed, and pumping modules
with a continuous radiation power of 760 W are produced. 相似文献

The possibility of controlled cyclic deflagration-to-detonation transition within a length of 2.5–3.0 m in an open-end tube
(94 mm in diameter) with separate continuous supply of natural gas and air was demonstrated for the first time. Based on experimental
studies, a workable pulse detonation burner, a prototype of new generation of industrial burners, was developed. It can produce
a combined effect on the objects blown on with combustion products—shock-wave (mechanical) and thermal. 相似文献

Based on detailed kinetic calculations and experimental data, it is demonstrated that the emission of nitrogen oxides from
detonation burner units (DBUs) is significantly lower than that from powerful conventional burners with similar characteristics.
Under certain conditions, realized largely in DBUs with rotating detonation, the main component of the nitrogen oxides may
turn out to be N2O. 相似文献

We study experimentally and theoretically short wideband antennas based on Vivaldi antennas in the form of a symmetric slot
transmission line with an opening width varying exponentially. The radiation patterns of a single emitter and a system of
two identical antennas are analyzed, and the influence of their geometric parameters on the shape of the radiation pattern
and wideband properties are studied.

Multidimensional simulations of the unsteady gasdynamic flow in the duct of an air-breathing pulse detonation engine (ABPDE)
operating on propane gas and the flow around it in supersonic flight at Mach numbers M of 3.0 and an altitude of 9.3 and 16 km are performed. It is shown that, at a length and diameter of the duct of 2.12 m and
83 mm, respectively, an ABPDE with an air intake and a nozzle can operate in a cyclic mode at a repetition frequency of 48
Hz, with a rapid deflagration-to-detonation transition (DDT) occurring at a distance of 5–6 combustion chamber diameters.
To determine the thrust performance of the ABPDE in flight conditions, a series of working cycles were simulated with consideration
given to the external flow around the engine. Calculations showed that the specific impulse of the ABPDE is approximately
1700 s. This value is much higher than the specific impulse typical of ramjet engines operating on conventional combustion
(1200–1500 s) and substantially lower than the specific impulse obtained for the atmospheric conditions at sea level at zero
flight velocity (∼2500 s). 相似文献

Total and differential cross sections for the exclusive reaction pp-->pp rho observed via the pi(+)pi(-) decay channel have been measured at p(beam)=3.67 GeV/c. The observed total meson production cross section is determined to be (23.4+/-0.8+/-8) mu b and is significantly lower than typical cross sections used in model calculations for heavy-ion collisions. The differential cross sections measured indicate a strong anisotropy (approximately cos(theta(CM)(rho)) in the rho(0) meson production. 相似文献
