Elektrostatično merjenje pnevmatskega transporta keramičnega prahu

Romih, Matic (author), Senegačnik, Andrej (mentor)

V magistrskem delu je obravnavana karakterizacija pnevmatskega transporta keramičnega prahu z elektrostatično merilno metodo, pri kateri je merilna sonda vstavljena v dvofazni tok. Z laboratorijskimi preizkusi smo preučevali glavne vplivne parametre na značilnosti pnevmatskega transporta ter ocenili merilno negotovost obravnavane metode. Izvedli smo multiregresijsko analizo in vzpostavili model, ki omogoča, da lahko ob poznavanju izmerjene elektrostatične napetosti in hitrosti nosilnega plina za material s poznanimi elektrostatičnimi lastnostmi določimo masni pretok prahu.

• Title: Electrostatic measurement of pneumatic transport of ceramic powder

Abstract

The present Master’s thesis presents the characterization of pneumatic transport of ceramic powder using electrostatic measuring method where the electrostatic probe is inserted into the two-phase flow. We examined the main influencing parameters on the characteristics of pneumatic transport and evaluated the measurement uncertainty of used method. We carried out a multiregresial analysis and established a model through which we can determine the mass flow of powder when we know the measured electrostatic voltage and velocity of the carrier gas for material with known electrostatic properties.
