  Solar spectral irradiance covers a fairly broad wavelength range. Solar radiation is part of the electromagnetic spectrum which is described by the concept of wave-particle duality. The corpuscular theory of electromagnetic radiation states that energy is transmitted by photons. Photons carry specific amounts of energy which can be used to convert solar energy into other types of energy, in particular electricity. The internal...

  - Year 2013

  Photocatalytic oxidation over suspended solid photocatalysts (e.g., titanium dioxide) has been proposed as a sustainable process for treatment and purification of water and wastewater as well as the process for photoconversion of solar energy to hydrogen, methane, and other low hydrocarbons. Solar radiation could be used to drive heterogeneous electrochemical reactions at the surface of an optically active photocatalyst (e.g.,...

  This work introduces the theoretical method of metallic nanoparticles’ (NPs’) heat and mass transfer where the particles are coated on a surface (base), together with considering the case wherein nanoparticles move freely in a pipe. In order to simulate the heat transfer, energy and radiative transfer equations are adjusted to the considered issue. NPs’ properties are determined following the nanofluidic theories, whereas absorption...

  W pracy przedstawiono zagadnienia modelowania fizycznego i numerycznego procesów wymiany ciepła i konwersji energii. Do analizy wymiany ciepła w przestrzeni wypełnionej płynem zastosowano termografie krystaliczne i komputerowy system analizy otrzymanych laserowych obrazów. Wykonano również termogramy powierzchni pokrytych także ciekłokrystaliczniei jako przykład przeanalizowano rozkład temperatury na powierzchniach ciał stałych...
