Experimental and numerical simulation of heat transfer and flow regimes for vertical flow across horizontal tubes are presented for mass flow rate in the range 0.03 – 0.17 kg/s and heat fluxes in the range 1.07–1.35 kW/m2. The tubes had a diameter of 9.75 mm and a pitch to diameter ratio of 1.85. Th...
