Linking morphology and rheology for structured fluids

对于工业结构化流体产品如洗涤剂和洗发水的制造，多尺度方法是必不可少的，以便在考虑这些产品的微观结构的同时获得这些产品的流变特性。液体微观结构与其流动性质之间的关系可以通过使用介观方法作为耗散粒子动力学来获得。博士项目将开发一种程序来获得常见表面活性剂/水体系的不同形态的粘度。总体目标是使用DPD来建立结构流体的结构-流变学关系。该项目由联合利华通过ICASE奖资助。

For the manufacture of commercial structured fluid products such as detergents and shampoos, a multiscale approach is essential so that the rheological properties of these products can be obtained while the microscopic structure of them is taken into account. The relationship between the liquid microstructure and its flow properties can be obtained by using a mesoscopic method as Dissipative Particle Dynamics.The PhD project will develop a procedure to obtained the viscosity of different morphologies of common surfactants/water systems. The overall aim is to use DPD to establish structure-rheology relationships for structured fluids. The project is funded by Unilever via an ICASE award.
