چکیده
Because of their compact structure, ease processing and higher heat transfer coefficient, curved-tube exchangers are widely applied in various industry applications, such as nuclear power systems, solar-powered engineering, aircraft engine cooling systems refrigeration cryogenic systems. Accurate knowledge about the characteristics supercritical fluids tube is critical to design optimization a exchanger. The available literature indicates that flow flowing curved tubes affected by dual effects buoyancy force centrifugal more complex compared straight tubes. Therefore, obtain insight into unique further research progress, this paper presents comprehensive review experimental numerical works on at pressure Overall, secondary caused curvature enhances delays deterioration, but it also causes non-uniform distribution along circumferential direction, strengthening performance damaged. Compared with mature theories regarding tubes, coupling mechanism force, general correlation still urgently need be studied. Most importantly, studies suppression oscillations inhomogeneities specific scarce. Considering current status shortcomings existing studies, some study topics for proposed.
