A method is presented to calculate the incident radiant heat flux and the temperatures reached on any point of a tank surface when this tank is engulfed in a pool-fire during the fire transitory state (developing phase). 1he method used to calculate the radiant heat flux on the cylinder is based on a three-dimensional formulation and uses the definition of a surface to establish the flame conto...

Sloshing flows in a two-dimensional rigid rectangular tank under specified excitations in the coupled horizontal and vertical modes are simulated by using a higher-order boundary element method BEM . The liquid sloshing is formulated as an initial-boundary-value problem based on the fully nonlinear potential flow theory. And a semi-mixed Eulerian-Lagrangian technique combined with the 4th-order...

Settling-thickening tanks are used to achieve separation of the liquid and solid fractions of faecal sludge (FS). They were fi rst developed for primary wastewater treatment, and for clarifi cation following secondary wastewater treatment, and it is the same mechanism for solids-liquid separation as that employed in septic tanks. Settling-thickening tanks for FS treatment are rectangular tanks,...

Abstract Two dimensional, selective withdrawal of a three-layer fluid in rectangular tank is considered. Each viscous, weakly compressible and miscible. The lowermost, heaviest flows with constant speed out through line sinks located on the base lower side walls tank. uppermost lightest recharges via sources along top upper at rate that matches outward flux. If are turned suddenly, interfaces b...

When disoriented in a closed rectangular tank, fish (Xenotoca eiseni) reoriented in accord with the large-scale shape of the environment, but they were also able to conjoin geometric information with nongeometric properties such as the color of a wall or the features provided by panels located at the corners of the tank. Fish encoded geometric information even when featural information sufficed...

Three-dimensional tank in smooth tank is of concern in various engineering applications. Sloshing waves in moving tanks have been studied numerically, theoretically and experimentally in past several decades and many significant phenomena have been considered in those studies, especially the linear and nonlinear effects of sloshing wave with inviscid or viscid liquid in a tank. The reported stu...

The effort to reduce costs and environmental impact of modern commercial aircraft requires an ever better understanding physics, including the characterisation effective damping introduced on a structure by slosh dynamics. In this paper experimental vertical sloshing dissipative behaviour rectangular tank, representative scaled wing is addressed. Specifically, controlled electrodynamic shaker e...

The focus of the present paper is on the development of a finite element formulation to investigate the sloshing of liquids in partially filled rigid rectangular tanks undergoing base excitation. The liquid domain is discretized into two-dimensional four-node rectangular elements with the liquid velocity potential representing the nodal degrees of freedom. Liquid sloshing effects induced by bot...

Quentin Skinner is an intellectual historian known for his pioneering work on early-modern European political thought. He was educated at Bedford School and Gonville and Caius College, Cambridge. Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...
