Authors: Pavel Bělík, Xueqing Su, Douglas P. Dokken, Kurt Scholz, Mikhail M. Shvartsman ABSTRACT In this paper, Beltrami vector fields in several orthogonal coordinate systems are obtained analytically and numerically. Specifically, axisymmetric incompressible inviscid steady state Beltrami (Trkalian) fluid flows … Continue reading
Authors: Muhammad Bilal, Yaolong Chen, Jun Zha, Naveed Ullah ABSTRACT Experimental and computational fluid dynamics (CFD) are investigated through the vortex tube system. The benefit of vortex tube is a counter flow type tube, which has further designed and fabricated … Continue reading
Authors: Shigeomi Chono, Tomohiro Tsuji ABSTRACT We investigate the flow induced by annihilation of a pair of defects in liquid crystals using the Doi theory with the Marrucci-Greco potential, in which the orientation state is described with the orientational distribution … Continue reading
Authors: John Uju Nwalor, Faith Uchenna Babalola, Vincent Okechukwu Anidiobu ABSTRACT Honey was serially diluted with different percentages of glucose, fructose and water and each was analysed rheologically at room temperature of 27°C. Pure honey exhibits thixotropic time-dependent rheological behaviour, … Continue reading
Author: Kyohei Shingai, Teruyoshi Sadahiro, Hidemi Yamada ABSTRACT A gate valve is one of the main elements of a circular pipeline, but the flow characteristics around the gate valve are hardly known. In this study, clarification of the flow field … Continue reading
Author: Takanori Uchida ABSTRACT In the present study, wind conditions were numerically predicted for the site of the Bolund hill using the RIAM-COMPACT natural terrain version software, which is based on an LES turbulence model (CFD). In addition, airflow measurements … Continue reading
Authors: M. Sereez, N. Abramov, M. G. Goman ABSTRACT Computational simulations of aerodynamic characteristics of the Common Research Model (CRM), representing a typical transport airliner are conducted using CFD methods in close proximity to the ground. The obtained dependencies on … Continue reading
Authors: Pavel Bělík, Douglas P. Dokken, Corey K. Potvin, Kurt Scholz, Mikhail M. Shvartsman ABSTRACT Processes related to the production of vorticity in the forward and rear flank downdrafts and their interaction with the boundary layer are thought to play … Continue reading
