Currently I am a Postdoctoral Fellow at the Non-Newtonian Fluid (NNF) Dynamics Research Group, located in
the Hatsopoulos Microfluids Laboratory with
the Department of Mechanical
Engineering at MIT .
My research is concerned with the development of an innovative triborheometry fixture/design to study the frictional dynamics of several solid-liquid systems,
such as skin substitute/lubricants and other natural products, for example banana skin peel. The triborheometry fixture/design includes
various hardware components; probably the most important are the helical springs of different stiffnesses. The fixtures are adapted to a commercial rheometer and the
experimental set-up is modified according to the system to test. By altering process conditions the effect of surface roughness/lubricant fluid enable us
to measure the coefficient of friction at different angular velocities and contact stresses for the different solid-liquid systems.
In this research, experimental details for the triborheology tests along with materials response are being obtained. From the data, quantitative explanations
for the Beam/Disc-coupling and material-structures design are given.
