Heat fluxes under the ceiling induced by wall fires with various burner aspect ratios in a channel

نویسندگان

چکیده

A detailed experimental investigation of wall fires in a channel was conducted to study the heat fluxes under ceiling. Various burner aspect ratios and fire release rates were employed simulate different scenarios. The effect source-ceiling height also examined. results show that distribution flux ceiling from on rectangular burners significantly influenced by ratio. As ratio increased, at given position perpendicular side increased. It found existing correlation developed for square could not capture such influence as it did include new predictive model based equivalent diameter concept proposed incorporating shown predict well all cases with rates, heights. validated against available data literature which used its derivation. Further analysis temperature contours constructed measurements

Simultaneous estimation of heat fluxes applied to the wall of a channel with turbulent flow using inverse analysis

The main purpose of this study is to estimate the step heat fluxes applied to the wall of a two-dimensional symmetric channel with turbulent flow. For inverse analysis, conjugate gradient method with adjoint problem is used. In order to calculate the flow field,   two equation model is used. In this study, adjoint problem is developed to conduct an inverse analysis of heat transfer in a channel...

Heat Transfer in Trapezoidal Microchannels of Various Aspect Ratios

Heat transfer in the thermal entrance region of trapezoidal microchannels is investigated for hydrodynamically fully developed, single-phase, laminar flow with no-slip conditions. Three-dimensional numerical simulations were performed using a finite-volume approach for trapezoidal channels with a wide range of aspect ratios. The sidewall angles of 54.7 and 45 are chosen to correspond to etch-re...

Heat Transfer with Viscous Dissipation in Couette-Poiseuille Flow under Asymmetric Wall Heat Fluxes

Analytical solutions of temperature distributions and the Nusselt numbers in forced convection are reported for flow through infinitely long parallel plates, where the upper plate moves in the flow direction with constant velocity and the lower plate is kept stationary. The flow is assumed to be laminar, both hydro-dynamically and thermally fully developed, taking into account the effect of vis...

Investigating structural, optical and photocatalytic properties of hydrothermally synthesized ZnO nanorod arrays with various aspect ratios

ZnO nanorods with various aspect ratios (by changing the time of growth between 0-240 min) were synthesized using hydrothermal method and were investigated using XRD, SEM, UV–Vis and PL. It was found that growth time is directly coupled with the length, orientation and aspect ratio of the nanorod arrays. The optical transmittance of the NR arrays indicated a regular decrement of average transmi...

Structural, Optical and Ultra-Violet Photodetection Properties of ZnO Nanorods with Various Aspect Ratios

ZnO nanorods with various lengths were synthesized by a two-stage route (by changing the time of growth between 0-240 min) and were characterized using XRD, SEM, UV–Vis and PL techniques. The SEM and XRD results confirmed a fast growth of (0 0 2) plane in the preferential longitudinal orientation, in contrast to lateral growth and therefore, by increasing the time of hydrothermal growth, nanoro...
