Due to the melt pool convection (
Marangoni effect), the particles are distributed and embedded homogenously.
This is more prominent when the angle of contact is large and is named the
Marangoni effect [54, 110-112].
[10] utilized their experimental and finite volume simulation results obtained from Mg alloy specimens to assert that a negative
Marangoni effect, due to the absence of the surface active agent in the alloy composition, makes the melt-pool wider and shallower.
The
Marangoni effect existing in the solvent-based coatings leads to volcanic defects [11].
Possible causal factors for global acceleration are Rayleigh-Taylor (R-T) instability [2], Kelvin-Helmholtz (K-H) instability [4], and critical Weber number theory [5], among others; the factor most commonly known to lead to local acceleration is the
Marangoni effect [6].
For conservation equations, the following assumptions were made: (1) the chemical reaction [23], thermal radiation [24], and
Marangoni effect [25] are ignorable; (2) air, iron, and slag are incompressible fluid [26]; (3) the interface of iron-slag in the taphole was kept as a horizontal surface, and slag was floated on iron because of lighter density; (4) the determination of the size of liquid droplets in another immiscible liquid was not done; and (5) the main trough of blast furnace was unattacked.
The
Marangoni effect and the Rayleigh-Benard effect cover large areas [5-7], included covering slags, contaminant transport, hypermonotectic alloy etc.
[17] found that the negative
Marangoni effect in the magnesium alloy composition enhanced the heat transfer in the molten pool by driving melt flows, making the molten pool shape wider and shallower.
This mass transfer is known as the
Marangoni effect [7].
The
Marangoni effect is the mass-transfer of the fluids with different surface tension along the interface.
An excellent view of the
Marangoni effect from the perspective of all three possible interfaces as motion inducing agents has been done by Tadmor [14].
This reaction is also known as the
Marangoni effect (the disturbance that the liquid-liquid interface, due to interfacial tension, has on mass transfer in a liquid-liquid extraction system).
