PIV measurements of flow in and around scour holes
Two sets of experiments related to the scour of cohesionless sediment by planar turbulent jets are presented and discussed. The first set of experiments measures the growth of the scour hole and downstream dune as a function of time. Measurements reveal a bedform that is nearly self-similar and whose growth in time is governed by a power-law relationship. The bedform is well represented by thre...
متن کاملPIV measurements of a microchannel flow
A particle image velocimetry (PIV) system has been developed to measure velocity fields with order 1-lm spatial resolution. The technique uses 200 nm diameter flow-tracing particles, a pulsed Nd: YAG laser, an inverted epi-fluorescent microscope, and a cooled interline-transfer CCD camera to record high-resolution particle-image fields. The spatial resolution of the PIV technique is limited pri...
متن کاملDevelopment of a Low Cost and Safe PIV for Mean Flow Velocity and Reynolds Stress Measurements
In this study, a white light particle image velocimetry (WL PIV) system which employs a light sheet generated with a flash was used. The system was developed in order to provide a cost-efficient and safe alternative to laser systems while keeping the accuracy limits required for hydraulic model tests. To investigate the accuracy of WL PIV method under different flow conditions, experiments were...
متن کاملSize Effects on the Entropy Production in Oscillatory Flow between Parallel Plates
The heat transfer problem of a zero-mean oscillatory flow of a Maxwell fluid between infinite parallel plates with boundary conditions of the third kind is considered. The local and global time-averaged entropy production are computed, and the consequences of convective cooling of the plates are also assessed. It is found that the global entropy production is a minimum for certain suitable comb...
متن کاملViscoelastic Effects on the Entropy Production in Oscillatory Flow between Parallel Plates with Convective Cooling
The heat transfer problem of a zero-mean oscillatory flow of a Maxwell fluid between infinite parallel plates with boundary conditions of the third kind is considered. With these conditions, the amount of heat entering or leaving the system depends on the external temperature as well as on the convective heat transfer coefficient. The local and global timeaveraged entropy production are compute...
