PT Journal AU SLEZIAK, M TI DIGITAL PARTICLE IMAGE VELOCIMETRY (DPIV) CORRELATION ALGORITHM SO Trends in education PY 2010 BP 581 EP 584 VL 3 IS 1 DE flow visualization; particle image velocimetry (PIV). AB This problem touches the aero-hydrodynamics issues deal with thermodynamic and floating processes within the heat exchangers. Modeling of these processes via dynamic fields of velocity and pressure visualizations is very useful for optimal design of mechanical constructions of equipments for many other applications [1, 2 etc.]. In this chapter the some aspects of digital particle image velocimetry (DPIV) based on vortex flows in quasi-regular heat-exchanging structures with the tracer-correlative technique are presented and considered. The classical shell-and-tube heat exchangers are commonly applied for heat transfer in flow [1, 3, 4]. ER
