Liftoff of a Co-Flowing Non-Premixed Turbulent Methane Flame: Effect of the Fuel Nozzle Orifice Geometry
Applied Scientific Research - Tập 92 - Trang 903-929 - 2014
This paper reports an experimental study on the effect of the fuel nozzle orifice geometry on the stability of turbulent non-premixed methane flame. Different internal geometries (orifice equivalent diameter, length to diameter ratio and contraction angle) of a circular and a rectangular nozzle with an aspect ratio of 2 were examined. The strength of the co-airflow was also varied to assess its im......
Mixed boundary value problem of heat conduction for infinite slab
Applied Scientific Research - Tập 16 - Trang 228-240 - 1966
An axisymmetric steady state heat conduction boundary value problem having mixed boundary conditions on both faces of an infinite slab, is reduced to a pair of Fredholm integral equations of the second kind. For large values of h, the slab thickness, a solution correct to O(h
−6) is obtained by expanding the kernels in power series.

The boundary layer flow of a Reiner-Rivlin fluid near a spinning cone
Applied Scientific Research - Tập 13 - Trang 194-202 - 1964
The steady motion of an incompressible inelastic Reiner-Rivlin fluid near a spinning cone has been studied and a similarity solution has been presented. It has been shown that the flow patterns can be obtained from Srivastava-Jain's work. But the pressure distribution is not the same and we have given the numerical values of the pressure in two tables and have also shown their variation in two fig......
Flow of second-order fluids over an enclosed rotating disc
Applied Scientific Research - Tập 15 - Trang 272-288 - 1966
This paper is devoted to a study of the flow of a second-order fluid (flowing with a small mass rate of symmetrical radial outflow m, taken negative for a net radial inflow) over a finite rotating disc enclosed within a coaxial cylinderical casing. The effects of the second-order terms are observed to depend upon two dimensionless parameters τ1 and τ2. Maximum values ξ1 and ξ2 of the dimensionless......
Large Eddy Simulation of Separated Flow over a Two-dimensional Hump with and without Control by Means of a Synthetic Slot-jet
Applied Scientific Research - Tập 83 - Trang 343-370 - 2009
Large Eddy Simulations for two flows separating from a two-dimensional hump in a duct are reported and discussed. The flows differ through the presence or absence of a synthetic slot-jet injected in a sinusoidal manner, i.e. at zero net mass-flow rate, close to the location of separation and intended to reduce (“control”) the extent of the separated region. Results reported include instantaneous v......
Boundary conditions for stokes flows near a porous membrane
Applied Scientific Research - Tập 52 - Trang 1-20 - 1994
A theoretical development is carried out to model the boundary conditions for Stokes flows near a porous membrane, which, in general, allows non-zero slip as well as normal flow at the surface. Two types of models are treated: an infinitesimally thin plate with a periodic array of circular apertures and a series of parallel slits. For Stokes flows, the mean normal flux and slip velocity are propor......
Theoretical study of the flowfield inside a hydrocyclone for higher Reynolds numbers
Applied Scientific Research - Tập 42 - Trang 3-13 - 1985
The axi-symmetric turbulent boundary layers formed on the conical surface and under the roof of different hydrocyclones have been studied for higher Reynolds numbers. Calculating the total flux through the boundary layers it has been found that the mathematical model for the flowfield, presented in a previous paper [2] for the 1/7th power law velocity distribution, holds even for higher Reynolds n......
