Thermodynamic and phase behaviour of fluids embedded with nanostructured materials

The effect of nanoparticles on the critical point shift for classical fluids embedded with nanostructured materials is examined. The low Global Warming Potential (GWP) industrial fluids + carbon nanotubes (CNT) systems are studied to estimate the critical point shift in the nanofluids with reference to pure components. Global phase behavior of two-component fluids with nanoparticles are analyzed and transformation from zeotropic to azeotropic state in the system R744/41 under the CNT doping is discussed.

► The presence of nanostructured materials in liquids changes their phase behavior. ► We examine critical point shift for classical fluids embedded with nanostructured materials (fullerenes and carbon nanotubes). ► The systems toluene + carbon nanotubes (fullerene) are studied to estimate the critical point shift of pure component. ► Phase equilibria of two-component fluids with nanoparticles are analyzed.
