We present a numerical model for dynamic simulation of colloidal particles attached to a fluid interface. A new coupling method is proposed for combining Newtonian dynamics for colloidal particles and the lattice Boltzmann method for fluid phases so as to account for the wetting properties of particle surfaces. With this feature, capillary interaction of colloidal particles, in addition to elec...

In the present work a two fluid model for blood flow through abnormally constrictedhuman artery (stenosed artery) has been developed. The model consists of a core region of suspensionof all erythrocytes assumed to be micro-polar fluid so as to include the micro-structural effects inaddition to the peripheral-layer viscosity effects, and a peripheral plasma layer free from cells of anykind of Ne...

A new homogenization approach for the simulation of multi-phase flows in heterogeneous porous media is presented. It based on lattice Boltzmann method and combines grayscale with multi-component Shan-Chen method. Thus, it mimics fluid-fluid solid-fluid interactions also within pores that are smaller than numerical discretization. The model successfully tested a broad variety single- two-phase f...

A thermodynamic property model explicit in the Helmholtz energy is presented for the R-134a/245fa mixtures. A multi-fluid approximation based on pure-fluid Helmholtz energy equations of state forms the basis of the property model. The Helmholtz energy of the mixture is expressed as the sum of the ideal gas contribution, the compressibility contribution (real fluid contribution), and the contrib...

Independence is achieved by using the extended extracellular fluid (Ecf) for dilution of hemoglobin (cHbB), reducing cHbB to cHbB / 3 (in the fetus to 1/4). Correction of ctHB from the normally low fetal oxygen saturation by reoxygenation of Hb increases ctHB resulting in four different variables: ctHB,act (= BEB), ctHEcf,act (Standard BE), ctHB,ox. and ctHEcf,ox. The question is which variable...

In this paper we consider a game-theoretic dynamic model describing the exploitation of a renewable resource. Our model is based on a Cournot oligopoly game where n profit-maximizing players harvest fish and sell their catch on m markets. We assume that the players do not know the law governing the reproduction of the resource. Instead they use an adaptive updating scheme to forecast the future...

Since the report of Crandall and Anderson (1) in 1934, the distribution of thiocyanate ion in the body has been used as a measure of extracellular fluid volume. All such work has been based on the procedure of administering a known amount of a thiocyanate, and after an interval, measuring the concentration of thiocyanate in the serum. The amount of thiocyanate injected, or more accurately, the ...

A central feature that scientists are interested in is the dynamics of fluid interfaces or the so called material boundaries in multi-fluid simulation . Visualization techniques for capturing fluid interface are based on one of about three basic algorithms. In this paper, we give a survey of the existing interface tracking algorithms, including backgrounds, terms, procedures as well as pointers...
