Theoretical and Numerical Modeling of Coating Flow on Simple and Complex Substrates including Rheology, Drying and Marangoni Effects

چکیده

We discuss the development of a comprehensive mathematical and numerical model for thin-layer flow of complex liquids on solid surfaces. The model includes physical and surface chemistry effects and allows direct prediction of the flow as it evolves in time, until the liquid has solidified. We pay particular attention to the substrate shape and wetting properties as well as viscosity dependence on flow stress and mixture composition. Important application areas are (i) decorative and protective coatings, and (ii) material processing. A particular research objective is the increased understanding of flow behavior that will aid in the design of new products and processes. Modeling results are shown for a number of problems, with experimental comparison, when available.

Role of Surface Tension Gradients in Correcting Coating Defects in Corners

normally has an uneven surface. When surface tension can Following the application of a liquid coating to a curved subbe considered to be uniform, capillary forces tend to reduce strate, surface tension forces will act to redistribute the coating surface irregularities to produce a level film. This is the layer. The coating will thin at outside corners and thicken at dominant effect leading to ...

Modeling of Anaerobic Digestion of Complex Substrates

A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-bat...

Three-Dimensional Direct Numerical Simulation of Surface-Tension-Gradient Effects on the Leveling of an Evaporating Multicomponent Fluid

Mathematical and numerical modeling of drying coating layers is of interest to both industrial and academic communities. Compositional changes that occur during the drying process make the implementation of practical and efficient numerical models rather difficult. In this paper we present a three-dimensional mathematical and numerical model based on the lubrication approximation for the flow o...

epl draft Threshold of Bénard-Marangoni instability in drying liquid films

We here show how evaporation/condensation processes lead to efficient heat spreading along a liquid/gas interface, thereby damping thermal fluctuations and hindering thermocapillary flows. This mechanism acts as an effective thermal conductivity of the gas phase, which is shown to diverge when the latter is made of pure vapor. Our simple (fitting-parameter-free) theory nicely agrees with measur...

Numerical modeling of three-phase flow through a Venturi meter using the LSSVM algorithm

One of the challenging problems in the Oil & Gas industry is accurate and reliable multiphase flow rate measurement in a three-phase flow. Application of methods with minimized uncertainty is required in the industry. Previous developed correlations for two-phase flow are complex and not capable of three-phase flow. Hence phase behavior identification in different conditions to designing and mo...
