Complex Liquid

A finite diffusion droplet evaporation model for complex liquid mixture composed of different homogeneous groups is presented in this paper. Separate distribution functions are used to describe the composition of each homogeneous group in the mixture. Only a few parameters are required to describe the mixture. Quasi-steady assumption is applied in the determination of evaporation rates and heat flux to the droplet, and the effects of surface regression, finite diffusion and preferential vaporization of the mixture are included in the liquid phase equations using an effective properties approach. A novel approach was used to reduce the transport equations for the liquid phase to a set of ordinary differential equations. The proposed model is capable in capturing the vaporization characteristics of complex liquid mixtures.

Improved Characteristics

The possibilities of the impedance method for the determination of microcomponents (microelements) in liquid media are considered. The method involves measuring the frequency characteristics of the active and reactive components of the impedance of a sample of liquid media in the range of measuring frequencies from 0.5 to 100 kHz and there by determines the trace elements in the medium. A variant of building a microprocessor impedance analyzer with improved characteristics for instrumentation support of the method under study is considered. Analyzed the features of the proposed analyzer.
