Rheology: The do's and don'ts
Participants will learn how to identify typical material characteristics in rheological data (yield stress, shear thinning, fracture, etc.).
Rheology is the study of flow and deformation of materials. Materials are everywhere: they are foods like mayonnaise and artificial meat. They are toothpaste gels, or concrete walls or glue on a post-it note or protein surfactants in an emulsion. Rheology is therefore a widely used tool relevant for both applied and fundamental research. The versatility of the subject makes that a broad understanding of the underlying concepts is essential to perform experiments and interpret data. This course aims to offer such a broad view.
The course is useful for persons who need to get involved in, or improve on their rheology experiments. An ideal knowledge background consists of the WUR courses FPH-10306, MAT-14803/14903, FPE-20806, PCC-20806, PCC-12303 and/or the equivalent basics in linear algebra, multivariable calculus, differential equations, physics of polymers/fluids and states of matter. A knowledge of Matlab and/or Python is helpful to do some of the (optional) exercises in data analysis.
After the course, we expect the participant to have obtained a broader knowledge of the basic considerations and concerns in rheological experimentation, data analysis and interpretation.
To this end, we will provide handles to develop an awareness of, and acquire the ability to identify common sources of error in experimental preparation, setup and execution. Also, participants should be able to identify the reliability interval in acquired experimental data, and extract material characteristics from such data.
The course consists of lectures of 2 hours, and a full day mini symposium. Participants will learn how to identify typical material characteristics in rheological data (yield stress, shear thinning, fracture, etc.). The course will touch upon how to combine multiple different rheological techniques/protocols to extend the necessarily limited range of a single protocol (super-position principles, creep/oscillatory test, different size tools). Additionally, we briefly cover how to combine rheological test information with other data types at simultaneous experiments (caber test, flow field data, birefringence, light scattering: DLS, X-ray, Raman).
The mini-symposium will feature a keynote lecture from Prof. Peter Fischer. Furthermore we will invite senior scientists from WUR to give talks on their rheology-related work. Participants can submit an abstract and be invited to give a short presentation on their work, where capacity allows.
