Figure 3.

(Top) Comparison of steady flame profiles at different confined flame conditions using black anodized aluminum baffles or no baffles, with a flow speed of 6 cm/s. When there is no baffle, the flame is situated between a transparent polycarbonate window and a black duct wall on the right and left side of a flame, as imaged, respectively. (Bottom) Overlayed profiles of the outer edge and center profile for each of the five flames. This figure is recreated from Li et al. (2021).

Figure 4.

Heat transfer coefficient as a function of time for the sawtooth microstructure (blue) and flat baseline (orange) surfaces at various heat fluxes. The applied heat fluxes are 0.7 W/cm2 (left), 1.0 W/cm2 (center), and 1.3 W/cm2 (right). The inset images show high-speed image frames captured during the experiment. The nearly constant heat transfer coefficient circled at the end of the sawtooth microstructure experiment at 1.0 W/cm2 is due to the constant temperature difference maintained between the surface and the fluid.

Figure 5.

A comparison of the vapor slug dynamics on the flat baseline surface (left) and the 60°–30° sawtooth microstructure surface (right) in microgravity at a heat flux of 1.3W/cm2. For the flat surface, the vapor slug covers the entire field of view, and no liquid layer is visible between the slug and the surface. For the sawtooth microstructure surface, there is a visible liquid microlayer across the crests of the sawteeth. The liquid layer is highlighted in the sawtooth microstructure schematic (bottom-right). Figure reproduced from Sridhar et al. (2024).

Figure 6.

Frequency as a function of static contact angle α (°) for several modes and substrates in microgravity. Experimental measurements are denoted by symbols, and theoretical predictions with free contact lines Λ = 0 are denoted by solid lines, where Λ is the mobility. The inset plot is the frequency for substrate P1 with pinned contact line Λ = ∞ (see McCraney et al., 2022b). The experimental error is ± 0.2 Hz, denoted by the symbol size.
