The dust particles contained in the industrial flue gas are discharged from many industrial
factories, which have seriously polluted the air and endangered the health of not only …

The performance of heat exchangers matters in the Brayton cycles for power and energy
storage systems. However, the understanding of how heat exchanger performances affect …

In this paper, numerical investigations on heat transfer and flow resistance characteristics of
a variable-direction twisted-oval tube (VDTOT) were performed. The effects of different …

The fouling problem of flue gas heat exchangers is one of the most critical problems to be
solved in industrial waste heat recovery applications. In this paper, the fouling potential …

In this paper, a W-type finned heat sink for natural convection is proposed based on the
research of inclined-plate fins. As thermal radiation considered, the natural convective heat …

The performance of the precooler in the supercritical CO 2 (S-CO 2) Brayton cycle may be
greatly affected by the interactions between the structure and the thermophysical properties …

To further enhance the thermal performance of double-tube heat exchangers, novel
arrangements of oval inner tube with alternate twist directions and different phase angles …

A large number of fly ash particles in flue gas easily cause the fouling problem of heat
exchangers, which seriously affects the efficient utilization of flue gas waste heat. In this …

A new configuration featuring an inner oval tube with alternating twist directions is proposed
to improve the thermal performance of double-tube heat exchangers. This design enhances …

In this paper, a new kind of herringbone wave fin with convex-strips in fin-and-tube heat
exchanger is experimentally and numerically studied. For comparison, a herringbone wave …
