Internal flue gas flow through a traditional Spanish wood-fired kitchen range (Hergóm Cocina Económica No. 7). The model is the gas volume only: firebox, gap under the hob, side channel next to the oven, channel under the oven, rear riser and flue spigot. Most internal dimensions are estimates, not measured. Steady incompressible flow, k-omega SST, gas properties approx. air at 300 °C, 12 Pa chimney draught at the outlet. Goal: find narrow sections and dead zones where soot and ash collect, and compare clean vs. clogged channels.
