Description:
|
Many colloidal solutions undergo structural transitions under shear and this behavior varies depending on whether the applied shear rate or the applied shear stress is varied smoothly. These materials are ubiquitous, yet we have very little understanding of their mechanical behavior. For example, Blood is one such colloidal solution which undergoes thrombus formation and lysis when subjected to shear due to a cascade of chemical reactions that are triggered due to shear. We have developed a constitutive model that is capable of capturing the response of such fluids. We now want to validate our model with data obtained from extensive rheological experiments. We are interested in the following tests – 1. Torque-controlled and Angular velocity-controlled tests in a parallel plate rheometer. 2. Torque-controlled and Angular velocity-controlled tests in a Bob and cup rheometer. 3. Large Amplitude Oscillatory Shear tests. |
