Original abstract
The main purpose of this work is the measurement of local heat fluxes (absorbed into water cooled walls) from confined non-premixed swirling gas flame. Presented are two thermal duties 745 kW and 1120 kW fired in a large-scale combustion chamber. Measured data are intended for use as a benchmark. Its purpose is to validate computational fluid dynamics (CFD) codes against reliable and transparent measurements. The uniqueness of reported measurements is in the scale of the experimental facility and its ability to provide accurate data at above thermal duties. The data uncertainty is also discussed. The experimental facility is described including complete geometry of the burner and combustion chamber to enable use of the measured data by other researchers. The entire geometry is made available in the STEP format.

Práce se zabývá měřením tepelných toků stěnou spalovací komory během difuzního, turbulentního, vířivého spalování zemního plynu. Jedná se o spalovací komoru průmyslových rozměrů. Uvedeny jsou dva výkonostní stupně hořáku 745 kW a 1120 kW. Naměřená data jsou určena pro validaci výpočetních kódů počítačové mechaniky tekutin (CFD).
