To give a theoretical background for understanding, formulation and solution of flow problems within mechanical and energy engineering

Introduction to basic principles of mass-, momentum and energy conservation in fluid mechanic systems. Conservation rules for control volumes. Fluid statics. Navier-Stokes and Euler equations in differential form. Bernoulli equation in the loss-less case. Vorticity. Stream function. Static, dynamic and total pressure. Dimensional analyses. Losses in piped flow and tube systems. Boundary layer theory, flow over a plane, basics atmospheric boundary layer flow. Aerodynamics of air-foils. Flow machines.

Lectures, supervised solving of training examples.

A student who has met the objectives of the course will be able to: - Describe fluid properties and characteristics. - Describe the classification of flows and distinguish laminar and turbulent conditions. - Perform basic calculations of static pressures and forces. - Describe the concept of volume control and its application. - Describe the terms in the Navier-Stokes equation. - Describe and perform basic applications of the Bernoulli equation. - Describe the concept of dimensionless numbers and their basic application. - Describe the concept of the viscous boundary layer and the respective pressures and forces and apply for the solution of basic problems. - Describe correlation-based equations for forces and pressure losses and apply for basic problems. - Describe efficiencies and energy losses in flows. - Perform basic calculations for losses in pipe flows for the example of water supply systems and the circulation heating systems. - Describe basic principles of flow machines – pumps, turbines and propellers – and their basic characteristics. - Describe efficiency characteristics of turbines and pumps and perform calculations for basic examples.
