Course content
- Thermal-comfort parameters of clothing. - Basic knowledge about transfer of fluids. Bernoulli equation. - Principles of steady - state transfer of heat by conduction, convection and radiation. - Thermal conductivity, thermal resistance, thermal diffusivity. Porosity and its influence on these parameters. - Heat transfer coefficient, boundary layer. Boundary conditions in heat and moisture transfer. - Principle of similarity and dimensionless numbers used for solution of heat and moisture transfer - Fourier´s equation of transient heat conduction and its solution of an endless slab by means of the separation of variables - Emission properties of materials. Laws by Wien and Stephan - Boltzman for the radiation heat transfer. - Moisture transfer, Fick´s laws, wetting and capillary wicking - Instruments for the determination of transient and steady - state thermos-physical parameters of materials - Specific parameters of textile fabrics influencing their transfer properties. The effect of moisture on these properties.
