Numerical Analysis of Oil Combustion in a Small Combustion DeviceZadravec, Matej (Avtor) Rajh, Boštjan (Avtor) Samec, Niko (Avtor) Hriberšek, Matjaž (Avtor) oil burneroil combustionmulticomponent reactive flowcomputational fluid dynamics (CFD)model validationThis paper focuses on the numerical analysis of the combustion of the liquid fuel Extra Light Fuel Oil (ELFO) in a small combustion device. The calculation was performed by ANSYS CFX computer code for experimental optimal air-fuel ratio (λopt) and the middle power of the oil burner Weishaupt WL5/1-A (37 kW). The goal of the numerical analysis was to establish, whether the experimentally determined λopt ensured the conditions for a complete combustion in each point of the combustion chamber. The comparison of numerical results and measured values confirm the suitability of the chosen numerical model.Univerza v Mariboru, Univerzitetna založba20142026-03-02 14:17:54Znanstveno delo97371sl
