Mohua Das

Mohua Das is a PhD candidate in mechanical engineering whose research is in the field of non- Newtonian fluid dynamics. As a MathWorks Fellow, she will pursue the following project: a study of strain-controlled, optimally windowed chirp rheometry. The goal of the project is to establish guidelines for selecting appropriate chirp parameters, enabling accurate and efficient capture of the rapidly evolving properties of transient materials. Understanding the microstructural changes that soft materials undergo during synthesis or assembly is crucial for linking these changes to macroscopic behavior and advancing material design. Her other recent work, which extensively utilizes MATLAB, developed a framework to enhance the accuracy of predicting the first normal stress difference using Laun’s empirical formula based on analyses utilizing the time-strain separable Wagner constitutive formulation and the fractional Maxwell liquid model. The knowledge derived from this study could be valuable for technological processes involving viscoelastic fluids. Mohua’s research could offer valuable new insights to advance materials design in many spheres.
