• Experimental Study on Mixed Combustion Characteristics of Methanol/Diesel Pool Fires in Engine Rooms of Hybrid Ships

  articleOpen access1st author

  Methanol/diesel hybrid−powered vessels represent a significant advancement in green and low−carbon innovation in the maritime transportation sector and have been widely adopted across various shipping markets. However, the dual−fuel power system modifies the fire load within the engine room compared to traditional vessels, thereby significantly influencing the fire safety of methanol/diesel−powered ships. In this study, anhydrous methanol and light−duty diesel (with 0 °C pour point) were used as fuels to investigate the mixed combustion characteristics of these immiscible fuels in circular pools with diameters of 6, 10, 14, and 20 cm at various mixing ratios. By analyzing the fuel mass loss rate, flame morphology, and heat transfer characteristics, it was determined that methanol and diesel exhibited distinct stratification during combustion, with the process comprising three phases: pure methanol combustion phase, transitional combustion phase, and pure diesel combustion phase. Slopover occurred during the transitional combustion phase, and its intensity decreased as the pool diameter or methanol fuel quantity increased. Based on this conclusion, a quantitative relationship was established between slopover intensity, pool diameter, and the methanol/diesel volume ratio. Additionally, during the transitional combustion phase, the average flame height exhibited an exponential coupling relationship with the pool diameter and the methanol/diesel volume ratio. Therefore, a modification was made to the classical flame height model to account for these effects. Moreover, a prediction model for the burning rate of methanol/diesel pool fires was established based on transient temperature variations within the fuel layer. This model incorporated a correction factor related to pool diameter and fuel mixture ratio. Additionally, the causes of slopover were analyzed from the perspectives of heat transfer and fire dynamics, further refining the physical interpretation of the correction factor.

• Plastic deformation of ceramics via quasistatic and high strain rate nanoindentation

  Journal of the American Ceramic Society · 2025-11-23

  article

  Abstract Nanoindentation testing conducted at low and high strain rates holds great promise as a technique for measuring strain rate sensitivity and exploring the plastic deformation mechanisms of ceramic materials that cannot be studied in standard tension tests because of their inherent brittleness. In this study, we employ a high strain rate nanoindentation testing system, combined with transmission electron microscopy, to investigate the intrinsic mechanisms of plastic deformation in two ceramic materials. The investigations encompass a wide range of indentation strain rates, spanning from a low of 10 −2 s −1 to a high of 10 4 s −1 , using single crystal MgO (111) and Al 2 O 3 (0001) as model materials. The results reveal that MgO exhibits a clear dependence of hardness on strain rate, while for sapphire, the influence of strain rate on hardness is negligible. The mechanisms underlying the distinct strain‐rate responses of the two materials were revealed through microstructural investigations beneath the indent. Overall, the results demonstrate the promise that nanoindentation testing techniques have for characterizing the plastic deformation of ceramics over a wide range of strain rates.

• STUDY ON THE INFLUENCE OF MULTI-FREQUENCY NOISE ON THE COMBUSTION CHARACTERISTICS OF POOL FIRES IN SHIP ENGINE ROOMS

  Heat Transfer Research · 2024-01-01

  article

  A large amount of low- and medium-frequency noise can be found in the engine room of a ship. However, during the development of a fire, vibrations of the air in the engine room at different frequencies can be caused by noise disturbances, and the flow field distribution in the flame zone will be changed, which will affect the combustion characteristics of the pool fire. In this paper, an n-heptane pool with a diameter of 6 cm in a confined space of 1500 mm × 1500 mm × 1000 mm is used. The effects of noise of 75 dB, 90 dB, 105 dB, and 112 dB at 250 Hz, 700 Hz, and 1000 Hz and the noise of the engine room on the combustion behavior of the pool fire are studied experimentally. The results of the analysis of the variation in fuel mass, flame height, and flame tilt show that the multi-frequency noise significantly affects the combustion characteristics of the pool fire in a confined space. Under the perturbation of noise waves, the fuel mass flux of the pool is larger than that of the pool fire when it burns freely, and the fuel mass flux is exponentially nonlinearly related to the noise pressure. In general, the flame height gradually decreases with an increasing noise pressure in the engine room. Additionally, a new coupling relationship between the flame height and the noise pressure is established based on the noise motion equation, and it is found that there is a negative exponential between the noise pressure and the flame height. In addition, the flame can tilt under the action of the air particle displacement caused by the noise of the engine room. The noise pressure field formed in the confined space has a restraining effect on the pool fire, and the flame tilt angle gradually decreases with an increasing noise pressure.
