Basic knowledge in the field of mathematics and physics

Scope

Lecture:

Description of physical bodies and phenomena by means of physical quantities; System of SI units; Equation of state. Description equilibrium states, types of forces, the concept of momentum, energy; Principles of substance behavior, energy conservation, equilibrium conditions (laws of thermodynamics). Examples of the use of substance and energy balance. D. Bernoulli equation. Types of transformation. The phenomenon of entropy and the principle of increase in entropy. Phase transitions. Rheology, surface tension, viscosity, "mass" forces. Balance conditions - Navier Stokes equation. Laminar and turbulent flows. Methods of energy transfer; heat, work, electromagnetic radiation, substance flow. Mathematical modeling of energy transfer processes in the manner of heat, convection, penetration. The specificity of biological fluid flows - non-Newtonian, pulsed flows. Interpretation of thermal and flow phenomena in biological systems (psychrometric effect, hydraulic resistance of blood flow, capillary phenomena, spontaneous phenomena of striving for balance, technical devices in the processing of energy types, refrigeration basins, heat engines, pumps, turbines, heat exchangers.

Project:

Numerical modeling of the influence of solution flow or temperature in a selected biological system. The student prepares the simulation of a given biological system, including its functioning with the implant. The project is divided into stages agreed with the lecturer.

 

Laboratory:

1. Measurement of liquid viscosity at variable temperature

2. Determination of molar reaction heat - calorimetric measurements

3. Numerical simulation of the blood flow in the human cardiovascular system

4. Numerical simulation of stationary heat flow in a rod using Ansys software.

5. Numerical simulation of unsteady heat flow in a heating plate using Ansys software.
