Schematic of the experimental setup. Representation of the assembly used for the high-pressure transcritical flow experiments. The setup includes two high-pressure syringe pumps, A and B, and a reciprocating pump for fluid circulation. The \(\mu\)PIV system consists of an inverted microscope, a CCD camera, a laser, a synchronizer, and a computer. Pressure and temperature measurement points are indicated at the inlet and outlet of the microchannel, represented as I & O, respectively. Additionally, an external CMOS camera is used for flow visualization. A detailed cross-section of the microscope plate assembly is shown at the top-right corner, depicting the microscope objective lens, the microchannel, and the heating system, which consists of a Peltier module, a copper heat transmitter, and two aluminum heat sinks to ensure thermal stability.
