Overview
Mission - The Laboratory of Hydraulics supports education in Fluid Mechanics and Hydraulics by providing the apparatus and infrastructure for reproduction, control and study /re-modelling of the basic flow phenomena in pressure-driven, free surface and underground flows, with applications in hydraulics and environmental engineering. Educational support is provided in the form of lab projects -short term (course exercises) and long term (theses). Prominent students are engaged through diploma theses in research activities both inhouse (JPSE2016, IPOR2019, ΑΜΜ2015, PSPM6_2013, TR), as well as within collaborative activities (e.g. Uni Stuttgart / Petrophysics). Part of these works are related to the ImproDeProF research project.
Location - Τhe Lab is located on the ground floor of Building C (C.011), Campus 2. The total surface is 175m2.
Equipment - Instrumentation and devices for measuring basic properties of fluids (density, viscosity, etc). A 6m flume of orthogonal cross-section (DxW) 30x7,5 cm2 with adjustable bed inclination and surface grade, and a 1,2m flume of adjustable bed (DxW) 20x4 cm2. Hydraulic benches and lab devices for controlled reproduction of hydraulic phenomena (see videos above) in pressure-driven ("tube") and free-surface ("open channel)" flows. A hydrodynamic rig (coupled pump/turbine/brake). Water-cycle surface and/or subsurface hydrology phenomena (precipitation, surface and/or soil drainage, imbibition, infiltration). Aerodynamics bench. Hydrology related equipment for field measurements in aqueducts and rivers, level meters, wind /rain /temperature-humidity gauges. Various auxiliary devices, pitot tubes, concentration sensors, digital pressure transducers. PIV (particle-induced velocimetry) system, wave probes. Also, fume hood, microscopes, constant temperature baths, chamber kilns and incubator, digital scales, etc.
