Analysis of five-hole probe calibration parameters

Karahan, Sema
Kutay, Ali Türker
Five-hole pressure probes are used to measure total and static pressure, magnitude and angles of flow velocity vector. Calibration procedure is of high importance to obtain ac- curate results. Different approaches are proposed in literature to obtain calibration coefficients and data reduction algorithm. In this paper, a significance analysis is conducted for the parameters of the third-order multiple regression model used in data reduction process. A new multi regression curve fitting is applied with the most significant parameters. The new reduced model gives more accurate results compared to the first-order regression whereas extensive data acquisition process of the third-order model is eliminated with reduced parameters.

Numerical Simulation of Reciprocating Flow Forced Convection in Two-Dimensional Channels
Sert, Cüneyt (ASME International, 2003-5-20)
<jats:p>Numerical simulations of laminar, forced convection heat transfer for reciprocating, two-dimensional channel flows are performed as a function of the penetration length, Womersley (α) and Prandtl (Pr) numbers. The numerical algorithm is based on a spectral element formulation, which enables high-order spatial resolution with exponential decay of discretization errors, and second-order time-accuracy. Uniform heat flux and constant temperature boundary conditions are imposed on certain regions of the ...
Numerical Solution and Stability Analysis of Transient MHD Duct Flow
Tezer, Münevver (2018-11-01)
This paper simulates the 2D transient magnetohydrodynamic (MHD) flow in a rectangular duct in terms of the velocity of the fluid and the induced magnetic field by using the radial basis function (RBF) approximation. The inhomogeneities in the Poisson’s type MHD equations are approximated using the polynomial functions (1+r) and the particular solution is found satisfying both the equations and the boundary conditions (no-slip and insulated walls). The Euler scheme is used for advancing the solution to ste...
Optimization of Vortex Promoter Parameters to Enhance Heat Transfer Rate in Electronic Equipment
Ayli, Ece; Bayer, Özgür (ASME International, 2020-04-01)
In this paper, optimization of the location and the geometry of a vortex promoter located above in a finned surface in a channel with eight heat sources is investigated for a Reynolds number of 12,500 < Re < 27,700. Heat transfer rates and the corresponding Nusselt number distributions are studied both experimentally and numerically using different vortex promoter geometries (square, circular, and triangular) in different locations to illustrate the effect of vortex promoter on the fluid flow. Optimization ...
Numerical solution of magnetohydrodynamic flow problems using the boundary element method
Tezer, Münevver (2005-03-18)
A boundary element solution is given for a magnetohydrodynamic (MHD) flow problem in a rectangular duct having insulating walls, in terms of velocity and induced magnetic field. The coupled velocity and magnetic field equations are first transformed into decoupled nonhomogeneous convection-diffusion type equations and then finding particular solutions, the homogeneous equations are solved using the boundary element method (BEM). The fundamental solutions of the decoupled homogeneous equations themselves are...
Study of jet quenching with isolated-photon plus jet correlations in PbPb and pp collisions at root s(NN)=5.02 TeV
Sirunyan, A. M.; et. al. (Elsevier BV, 2018-10-01)
Measurements of azimuthal angle and transverse momentum (p(T)) correlations of isolated photons and associated jets are reported for pp and PbPb collisions at root s(NN) = 5.02 TeV. The data were recorded with the CMS detector at the CERN LHC. For events containing a leading isolated photon with p(T)(gamma) > 40 GeV/c and an associated jet with p(T)(jet) > 30 GeV/c, the photon+jet azimuthal correlation and p(T) imbalance in PbPb collisions are studied as functions of collision centrality and p(T)(gamma). Th...
