In room–corridor building geometry, the corridor smoke temperature is of great importance to fire protection engineering as indoor fires occur. Theoretical analysis and a set of reduced-scale model experiments were performed, and a virtual fire model was proposed, to investigate the correlations between the maximum smoke temperature in corridors and the smoke temperature in rooms. The results s...

Abstract In this work, the effects of externally applied axial pressure gradients and transverse magnetic fields on electrokinetic energy conversion (EKEC) efficiency streaming potential nanofluids through a microannulus are studied. The analytical solution for electro-magneto-hydro-dynamic (EMHD) flow is obtained under condition Debye-Hückel linearization. Especially, Green’s function method u...

In the present numerical study, thermal performance and fluid flow properties have been investigated to show effect of single-orifice multiple-orifice impingement synthetic jets for dimensionless orifice-toplate distance (H/D) lower than one. Investigations done an actuation frequency f=500 Hz, 0.10 ≤ H/D 0.75, pitch ratio 1.25 Do/D 1.75. The results were validated with experimental from litera...

This article examines the time duration of individual occasions in light discovery that temporal succession produces frequency ratios. The ratios are used to define energy and quantum. manifold common particles constructed graphically using arrows time, with mass-ratios derivable from graphs. formal reduction physics compels us adopt Whitehead's conception physical universe as experience engage...
