Anumerical model based on Cahn–Hilliard phase-field method is introduced for thefirst time in the literature to investigate the hydrodynamics and heat transfercharacteristics of a vaporized elongated bubble in a rectangular microchannel. In thesimulations, the initially nucleated bubble starts growing as it comes in contact withsuperheated water. The effects of the water inlet velocity and the bubble contact angleon the temporal evolution of the average heat transfer coefficient are also reported.Both qualitative and quantitative comparisons indicated that the numerically obtainedbubble shape and the growth rate are in very good agreement with the experimentalresults available in the literature.

Numerical investigation of coupled heat and mass transfer inside the adsorbent bed of an adsorption cooling unit Solmus, Ismail; Rees, D. Andrew S.; Yamali, Cemil; Baker, Derek Keıth; KAFTANOĞLU, BİLGİN (2012-05-01) In this study, the influence of several design parameters on the transient distributions of temperature, pressure and amount adsorbed in the radial direction of a cylindrical adsorbent bed of an adsorption cooling unit using silica gel/water have been investigated numerically. For this purpose, a transient one-dimensional local thermal non-equilibrium model that accounts for both internal and external mass transfer resistances has been developed using the local volume averaging method. For the conditions in...
Nano-organic carbon and soot particle measurements in a laminar ethylene diffusion flame D'Anna, A; Rolando, A; Allouis, Christophe Gerard; Minutolo, P; D'Alessio, A (2005-01-01) The formation of carbonaccous particulates in a co-flow laminar diffusion flame has been studied using UV-visible spectroscopy and laser scattering/extinction techniques for measurements of volume fractions and particle sizes. Measurements were performed in a non-smoking ethylene-air flame at atmospheric pressure. UV-visible spectroscopy allowed the identification of two classes of particles: soot particles, which absorb light in the whole spectral range and nano-organic carbon particles (NOC) which are tra...
Numerical and experimental investigation of quench process Gür, Cemil Hakan; Ozturk, T (1996-11-07) Numerical and experimental studies have been carried out to investigate the evolution of residual stresses in quenched components induced by temperature gradient and phase transformations. In the numerical analysis, a finite element model is implemented for predicting the temperature field, phase changes with their associated internal stresses in axisymmetrical steel components. The model is verified by several comparisons with other known numerical results. Case studies are performed to investigate the eff...
Ionic conductivity of microporous titanosilicate ETS-10 and ion-exchanged Mn+-ETS-10 (where, Mn+ = Li+, Na+, Mg2+, Zn2+, Ca2+) thin films prepared by secondary growth method Galioglu, Sezin; Çam, İbrahim; Akata Kurç, Burcu (2017-09-15) Impedance spectroscopy was used to investigate the long-range ionic conductivity of the microporous, titanosilicate (Na,K)-ETS-10 and ion-exchanged Mn+-ETS-10 (where, Mn+ = Li+, Na+, Mg2+, Zn2+, Ca2+) thin films prepared by secondary growth method. To figure out the effect of grain boundary on ionic conduction, as-synthesized (Na,K)-ETS-10 films possessing different thicknesses of columnar grain structure (i.e., films prepared via 4h-, 6h-, 8h-, and 10h-growth) were tested. The conductivities of the films w...
Failure analysis of shear critical RC structural members Sarıtaş, Afşin (2004-06-01) This paper presents a beam finite element for the simulation of the monotonic and cyclic response of RC structural members under the interaction of flexure, axial force and shear. The proposed beam element follows the assumptions of the Timoshenko shear beam theory with a three-field Hu-Washizu variational formulation for the derivation of the element response. The nonlinear response of the element is obtained through section integration of nonlinear material response. A 3d plastic damage model for cyclic a...
