Avoid long periods, bulleted lists are preferable Figure 1 shows the test cell sketch and thermocouples location. Figure 1. All labels in the sketch should be readable. Figures should be quoted in the text NUMERICAL MODEL: Be concise. Avoid long periods, bulleted lists are preferable Figure 2. All labels and symbols in the plots should be readable. All equations should be numbered and quoted in the text. Table 1. Code input parameters. Input parameter Value Working fluid FC-72 Tube material Copper Internal diameter 1.1 mm External diameter 2 mm Surface roughness 50 μm Evaporator length 6 mm Condenser length 180 mm Filling ratio 0.5 Gravity acceleration 1g, 2g, 10g External temperature 20 °C External HTC 300 W/m2K Heat power 50 W 𝑓 𝑥 = 𝑎 0 + 𝑛=1 ∞ 𝑎 𝑛 cos 𝑛𝜋𝑥 𝐿 + 𝑏 𝑛 sin 𝑛𝜋𝑥 𝐿 (1) RESULTS: The simulated pseudo-steady state values in term of temperature and pressure are closed to the ones experimentally observed (max error < 10°C) as shown in figure 2. Equation (1) is the Fourier Series of the function f(x). CONCLUSIONS: Briefly define the research outputs and or the objectives fullfillment. Avoid long periods, bulleted lists are preferable
