Quantifying Plasticity and Temperature in High Velocity Microparticle Impacts
… setup that enables in-situ observation of micron-scale particles impacting targets at velocities ~10-1500 m/s. Through a combination of the high velocity and small length-scale of the impact, strain rates exceeding 10⁷ /s can be achieved while maintaining a subsonic plastic wave, preventing …

Numerical Study of Mixing of a Supercritical Jet in a Supercritical Environment
… core penetration and identification of turbulent length scales. These data are compared with experimental data and evaluated against other modeling approaches. Mixing behavior is expected to mimic that of a single-phase jet, and be diffusion-driven, as there will be no droplet formation in the …

Characterization and design of non-adiabatic micro-compressor impeller and preliminary design of self-sustained micro engine system
… of the first effect is a result of the engine small length scale selection and is characterized by the total heat to impeller flow as fraction of inlet flow enthalpy. The magnitudes of the last two effects can be attributed to low Reynolds number. Scaling laws for elucidating the parametric …

High throughput prototyping and multiscale indentation characterization of metallic alloys
… techniques. In addition, the hierarchical multiscale structure of advanced materials holds the key to improving their performance characteristics. In order to understand and characterize microscale constituents, and length scale effects, novel high throughput approaches are necessary to explore …

Understanding the effect of protonation on the self-assembly of a model polyelectrolyte-neutral block copolymer
… limited due to the lack of long range order and small length scale of the structural inhomogeneities. Moreover, the charge functionality is typically introduced in a permanent way that is not modifiable after synthesis, locking in a chemistry and structure that may not be optimal for the ultimate …

Numerical optimisation and theoretical analysis of complex microchannel heat exchangers
The purpose of this study is to evaluate the performance of the geometries in forced convective heat transfer and steady state laminar incompressible fluid flow. Microchannel heat sinks used were numerically modelled from highly conductive (aluminium) solid material substrate. ANSYS FLUENT Response …
