“…We studied 18Mn2 ferrite-pearlite low-carbon plate steel in the initial state and after 10 and 30 yr of operation [8] and SSAB Domex medium-carbon steel microalloyed with boron (0.28% C, 0.25 Si, 1.21 Mn, 0.53 Cr, and 0.0033% B). For testing, we used vibratory equipment with stationary specimen based on a VCX-500 Sonics ultrasonic processor [9] and cylindrical specimens 13 mm in diameter and 4-5 mm in height.…”

We recommend to use SSAB Domex steel microalloyed with boron and characterized by elevated resistances to corrosion-erosion fracture and low-cycle fatigue instead of the widespread 18Mn2 steel in the water transport and elements of hydroengineering structures subjected to the action of strong water flows including, in particular, the Kort nozzles, rudder drives, and parts of the river-ship hulls especially sensitive to erosion.

“…In [21] Barbulescu et al have proved a relation between electric phenomena in cloud cavitation and pressure pulsations generated by a piezoelectric transducter. In paper [22] a method for the separation of electrical pulses associated with pressure pulses from electrochemical noise (fig. 9) generated in cavitation test conditions at a vibratory rig with a stationary specimen.…”

“…However, none of the works mention how to avoid sediment on the bottom of the engine cooling channel of "light" nanoparticles under the action of inertial and gravitational forces. The main questions addressed in the article are the following: factors influencing the thermal conductivity coefficient of nanofluids (including very high value in pure hydrogen or hydrogen containing); boiling of liquid in the cooling jacket of the engine cylinder head; behavior of nanoparticles and devices with nanoparticles in the engine cylinder head cooling system; the discussion of the results , taking into account degradation of modern structural materials under the hydrogen containing environment influence [2,24,32,[43][44][45][46][47][48][49][50][51]63,118,175,176].…”

The article is devoted to the following issues: boiling of fluid in the cooling jacket of the engine cylinder head; agents that influenced the thermal conductivity coefficient of nanofluids; behavior of nanoparticles and devices with nanoparticles in the engine’s cylinder head cooling system. The permissible temperature level of internal combustion engines is ensured by intensification of heat transfer in cooling systems due to the change of coolants with “light” and “heavy” nanoparticles. It was established that the introduction of “light” nanoparticles of aluminum oxide into the water in a mass concentration of 0.75% led to an increase in its thermal conductivity coefficient by 60% compared to the base fluid at a coolant temperature of 90 °C, which corresponds to the operating temperature of the engine cooling systems. At the indicated temperature, the base fluid has a thermal conductivity coefficient of 0.545 W/(m °С), for nanofluid with particles its value was 0.872 . At the same time, a positive change in the parameters of the nanofluid in the engine cooling system was noted: the average movement speed increased from 0.2 to 2.0 m/s; the average temperature is in the range of 60–90 °C; heat flux density 2 × 102–2 × 106 ; heat transfer coefficient 150–1000 . Growth of the thermal conductivity coefficient of the cooling nanofluid was achieved. This increase is determined by the change in the mass concentration of aluminum oxide nanoparticles in the base fluid. This will make it possible to create coolants with such thermophysical characteristics that are required to ensure intensive heat transfer in cooling systems of engines with various capacities.
