Abstract:
An integral method to determine infinite dilution activity coefficients [Formula: see text] from data sets of finite concentration activity coefficients is proposed for binary systems. This method is based upon the integration of the experimental dependence of ln [Formula: see text] over different composition ranges. The limiting behavior of this function is analysed, in order to improve the precision of its integration. The accuracy of this method is demonstrated by the calculation of [Formula: see text] for several systems.

A knowledge of diffusion coefficients in liquids is important from engineering as well as theoretical aspects. Molecular diffusivities can be used in predicting the mass transfer coefficients for the design of equipment for separation processes. The diffusion process may determine the rate at which these processes take place. The understanding of the diffusion process is important from a theoretical standpoint in helping us to understand the structure of liquids, the mechanism of diffusive transport and to test the validity of existing theories of diffusion.

On the other hand, data of activity coefficient at infinite dilution is an important part of dilute-end vapor liquid equilibrium data. When available, it can be used to solve for parameters in many activity coefficient models which may in turn determine the vapor liquid equilibrium behavior for the entire concentration range.

Abstract During gas injection in ultra-tight fractured reservoirs, molecular diffusion can play a dominant role in the mass transfer process and enhance recovery by extracting oil components from matrix and delaying gas breakthrough.

However, many fundamental questions pertaining to the physics of multicomponent multiphase flow and transport are still left unanswered. This paper aims to improve the understanding of m

The hydrogen dilution in the reformate gas calls for a modification of the fuel cell feeding system.

Abstract:
Combustors with fuel-spray atomisers are particularly susceptible to a low-frequency oscillation at idle and sub-idle conditions. For aero-engine combustors, the frequency of this oscillation is typically in the range 50-120Hz and is commonly called ‘rumble’. The mechanism involves interaction between the plenum around the burner and the combustion chamber. Pressure variations in the plenum or the combustor alter the inlet air and fuel spray characteristics, thereby changing the rate of combustion. This in turn leads to local ‘hot spots’ which generate pressure oscillations as they convect thr
