Sentence examples for base fluid as a from inspiring English sources
This work proposes the use of nanofluids, colloidal suspensions of nanoparticles in a base fluid, as a heat transfer fluid for active thermal management.
However, in the case of aggregation of particles in nanofluids, the measured near-wall velocities would be different when compared with that of the theoretical and experimental base fluid as a result of non-homogeneous nature of the flow.
where keff(L,T, φ) is the effective thermal conductivity of the nanofluid as a function of particle size (L), temperature (T), and particle volume fraction, kl(T) is the thermal conductivity of the base fluid as a function of temperature, and kP L,T) is the thermal conductivity of the particle as a function of particle size and temperature.
The effect of the ratio of buoyancy forces on heat and mass transfer of nanofluid possesses some similarities with the pure base fluid as well as some obvious differences.
The value of the measured specific heat C p of the base fluid as well as the nanofluids are comparable (C p ≈ 2.5 J/g K).
Heat transfer enhancement can be up to 2.4 times that of the base fluid as far as CHF values are concerned.
This is due to the fact that the SDS dispersant significantly suppresses the thermal conductivity of the base fluid, as was seen in Figure 5.
These temperature variations are very similar for both nanocrystalline structures and the base fluid, as can be appreciated in this figure.
Such an increase mainly depends on factors such as the form and size of the particles and their concentration, the thermal properties of the base fluid as well as those of the particles, kinetics of particle in flowing suspension, and nanoparticle slip mechanisms.
Viscosity of the fluids also increases with the augment of the nanoparticles concentrations [5, 6] when nanoparticles are dispersed into the base fluids as well.
Choi [1] in his pioneering work indicated that when a small amount of nanoparticles is added to common base fluids, it increases significantly the thermal conductivity of the base fluids as well as their convective heat transfer rate.
