In this paper sound propagation through an air-filled circular duct containing water droplets has been studied by solving numerically one-dimensional linearized Euler equations in frequency domain. Interactions between the liquid and gas phases were accounted for by proper source terms. Waves were introduced into the domain via Perfectly Matched Layers (PML) equations applied in finite regions adjacent to the truncated ends of the duct. Absorption and dispersion results due to energy transfer from air to the water droplets were obtained as a function of average droplet diameter and droplet concentration as well as finite mass loading. Results agree well with those available in the literature.

Exact solutions for vibrational levels of the Morse potential Taşeli, Hasan (IOP Publishing, 1998-01-16) The vibrational levels of diatomic molecules via Morse potentials are studied by means of the system confined in a spherical box of radius l, II is shown that there exists a critical radius l(cr),, at which the spectrum of the usual unbounded system can be calculated to any desired accuracy. The results are compared with those of Morse's classical solution which is based on the assumption that the domain of the internuclear distance r includes the unphysical region (-infinity, 0). By determining numerically...
Numerical simulation of radiating flows Karaismail, Ertan; Selçuk, Nevin; Department of Chemical Engineering (2005) Predictive accuracy of the previously developed coupled code for the solution of the time-dependent Navier-Stokes equations in conjunction with the radiative transfer equation was first assessed by applying it to the prediction of thermally radiating, hydrodynamically developed laminar pipe flow for which the numerical solution had been reported in the literature. The effect of radiation on flow and temperature fields was demonstrated for different values of conduction to radiation ratio. It was found that ...
Numerical investigation of unsteady natural convection from a heated cylinder in a square enclosure Bozkaya, Canan (null; 2015-07-06) A numerical study of two dimensional, unsteady, incompressible natural convection flow and heat transfer is performed in a square enclosure involving a heated circular cylinder. The natural convection is driven by a temperature difference between the cold outer square and hot inner circular cylinders. The temperature of the inner cylinder varies sinusoidally with time about a fixed mean temperature while the outer enclosure is kept at a lower constant temperature. The problem under consideration, which is g...
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...
Numerical studies of the electronic properties of low dimensional semiconductor heterostructures Dikmen, Bora; Tomak, Mehmet; Department of Physics (2004) An efficient numerical method for solving Schrödinger's and Poisson's equations using a basis set of cubic B-splines is investigated. The method is applied to find both the wave functions and the corresponding eigenenergies of low-dimensional semiconductor structures. The computational efficiency of the method is explicitly shown by the multiresolution analysis, non-uniform grid construction and imposed boundary conditions by applying it to well-known single electron potentials. The method compares well wit...
