While existing engineering tools enable us to predict how homogeneous surface roughness
alters drag and heat transfer of near-wall turbulent flows to a certain extent, these tools …

Direct numerical simulations of laminar boundary layer flow on a flat plate with arrays of
tetrahedral vortex generators (VGs) for heat transfer enhancement have been carried out to …

Understanding heat transfer is important for developing high-performance internal
combustion engines, but heat transfer mechanisms have not yet been elucidated. The …

Reducing the cycle-to-cycle variation in an engine is a key to expanding the operational
limits of high-efficiency engines such as lean-burn engines. The cycle-to-cycle variation of …

We introduce a measurement concept using seeded thermographic phosphor particles,
which achieves high spatial resolution and rejection of surface induced signals, and is …

Laser absorption Doppler velocimeters use a crossed-beam configuration to cancel errors
due to laser frequency drift and absorption model uncertainty. This configuration complicates …

It is essential to quantify the physical properties and the dynamics of flowing particles in
many fields, especially in microfluidic-related applications. We propose phase image …
