Presented herein is a comparative performance analysis of novel turbofan engine with an auxiliary combustion chamber, nicknamed the TurboAux engine, against turbojet and low bypass ratio afterburner presented. The adaption low-bypass but secondary in annular chamber for thrust augmentation. envisioned desire to facilitate clean burning fuel at temperatures higher than main air exiting low-press...

We revisit the search for heavy neutral leptons with Big European Bubble Chamber in 1982 proton beam dump experiment at CERN, focussing on those heavier than kaon and mixing only tau neutrino, as these are far less constrained their counterparts smaller mass or other mixings. Recasting previous terms of this model including additional production decay channels yields strongest bounds to date, u...

The article considers the problem of calculation accuracy when using mathematical models gas-turbine engines second level complexity, example a device for mixing flows core engine and bypass duct gas turbine engine, suggests methods solving it. processes taking place in chambers air-breather are considered to be difficult modeling since exchange kinetic thermal energies characterized by differe...

Abstract High-pressure homogenization is the state of art to produce high-quality emulsions with droplet sizes in submicron range. In simultaneous and mixing (SHM), an additional stream inserted into a modified nozzle order create synergies between unit operation mixing. this work, influence on cavitation patterns after cylindrical orifice investigated. Shadow-graphic images were taken using hi...

A dry, low-NOx (DLN) combustor for a heavy-duty gas turbine using lean premixed technology was studied. high-fidelity test model built the experimental study particle image velocimetry (PIV). The non-reacting flow in DLN combustion chamber investigated experimentally and numerically. numerical results are good agreement with data. show that recirculation zones were formed downstream of each swi...

CHAMBERS ACOUSTIC STABILITY Vladimir Bazarov Moscow Aviation Institute (State Technical University) 4, Volokolamskoe Shosse, Moscow 125080, RUSSIA E-mail: [email protected] Abstract Comparative analysis of the injector development history in order to eliminate acoustic instability in combustion chambers of LOX/kerosene big thrust engines both of gas generator and staged combustion cycle such as F-1, ...

The six-chamber cardiovascular system model of Burkhoff and Tyberg has been used in several theoretical and experimental studies. However, this cardiovascular system model (and others derived from it) are not identifiable from any output set. In this work, two such cases of structural non-identifiability are first presented. These cases occur when the model output set only contains a single typ...

chamber; construction of an outer box; building of an air filter; assembly of an inside of the box; doors and the electric devices. Decomposition begins within the upper mixing chamber, with the help of microorganisms, during the first nine days. The curing process then continues in the lower chamber for the remaining five days. The Green Machine was a success for it created organic soil in fou...

Even though microfluidics has been successfully used in minimizing complicated and onerous processes, the pumping and tubing systems used with it are yet undeveloped and need immediate development. The present study developed a fluttering bar-driven micropump, mounted on a polydimethylsiloxane microfluidic system. The pump consists of a rectangular ferromagnetic bar and a fan-shaped chamber wit...
