In this study, attempts have been made to utilize ammonia in the industrial heating field, which highly preheated air around 1000°C is used under high temperature atmosphere inside furnace 1200°C. The inlet and are realized bench-scale furnace. Ammonia methane fraction of 30%-NH3 70%-CH4 based on lower value, corresponding volumetric 55%-NH3 45%-CH4 as fuel fixed thermal input 40-kW. On furnace, nozzle burner installed nozzles inner side annular nozzle, furthermore, injection called "F2...
The transition to turbulence in the boundary flow of superfluid $^{4}\mathrm{He}$ is investigated using a vortex-free vibrating wire. At high wire vibration velocities, we found that stable alternating around enters turbulent phase triggered by free vortex rings. Numerical simulations dynamics demonstrate rings can attach surface an oscillating obstacle and expand unstably due superfluid, forming turbulence. Experimental investigations indicate continues even after stopping injection rings,...
Turbulence in boundary layers of superfluid $^{4}\mathrm{He}$ is studied using a vibrating wire. We developed vortex filtering method for providing practically free remanent vortices which wire cannot generate turbulence. Based on this superfluid, we find that lines are nucleated by cooling through the transition and remain forming bridges between surrounding wall. Vibration causes instability bridged lines, generating Dense produce nonlinear modes vibration, very sensitive to temperature,...
