BRA003 course is part of 1 study plan
BPC-SI / V Winter Semester 3rd year
The course deals with determination of effects of water on plane and curved surface and information on floatation of bodies.
Findings about flow and motion of water in pipe pressure systems and in systems with free water surface (i.e. flow in natural and artificial open channels). Hydraulics of water structures.
Steady non-uniform and unsteady continuously changing flow in open channels and pipes, filling and emptying of non-prismatic reservoirs and lock chambers. Hydraulics characteristics of the shaft and lateral spillways. Chutes, types of hydraulic jump and design of stilling pools.
Basics of model similitude in fluid mechanics. Selected chapters of object hydraulics and pressure systems hydraulics.
Practical aspects of groundwater flow, principles of continuity. Assumptions accepted for ground water flow solution, simple water intakes, simple models of flow through a dam, solution of system of wells.
The findings are applied in computational and laboratory exercises.
2. Mechanical energy losses caused by liquid flow. Influence of hydraulic elements distance on the mechanical energy losses.
3. Free and submerged water jets, flow around bodies. Action of water flow on surfaces. Application of impulse theory.
4. Overflow of basic and special types of weirs, movable spillway constructions capacity. Overflow of water with high submergence factor.
5. Emptying of tanks, non-prismatic reservoirs. Filling and emptying of lock chambers. Continuously changing unsteady flow. Shock waves in open channels. Shock waves in pipes, direct and indirect hydraulic shock. Time slope of shock wave.
6. Pipe systems, pump design, flow cavitation.
7. Hydraulic jump in prismatic and non-prismatic channel. Supercritical flow in channels and spillways, aeration of water flow.
8. Flow in bridge profiles and culverts.
9. Shock waves in open channels. Shock waves in pipes, direct and indirect hydraulic shock. Time slope of shock wave.
10. Flow close to inlets, downflow baffle.
11. Flow of non-newton fluids, bingham and non-bingham matter flow.
12. Basics of model similarity in fluid mechanics. Limit conditions of the similarity on the hydraulics models.
13. Darcy’s equation, filtration coefficient, specific leakage and mean velocity of water flow in voids. Hydraulics of wells in steady state.
