In a confined space, the flammability of alternative refrigerants (such as R717, R290, R32, and R1234yf) poses significant safety risks during leaks. However, in actual refrigeration systems, direction refrigerant leakage is difficult to predict, complicating explosion risk assessment. this work, R1234yf were selected research objects analyze diffusion process deposition characteristics different leaking vertically upward into explore migration flammable under amounts area space. The results show that after vertical leakage, tend impact top wall then move along away from leak source. High-density diffuse primarily near floor, while less dense diffuses side After stops, R1234yf, with highest density, exhibited most pronounced deposition, concentration floor lowest at (1.69% 0.7%, respectively). Conversely, lower-density showed decreasing concentrations increasing concentrations, reduced overall deposition. Compared R290 bottom room (1.32%), R744 demonstrated higher than likely due its viscosity similar densities. addition, using an example, study reveals increase amount prolonged time result gradual expansion area, encompassing walls, floor.

Within the energy sector, potential to effectively harness considerable present in gas turbine waste heat via an organic Rankine cycle (ORC) could markedly improve overall efficiency. This investigation centers on a printed-circuit exchanger (PCHE) utilizing cyclopentane as working fluid. The study employs combination of experimental techniques and computational fluid dynamics (CFD) simulations conduct in-depth analysis PCHE’s performance, leading successful development highly accurate heat-transfer correlation. A thorough comparison simulation data is carried out examine temperature pressure distributions within exchanger. maximum deviation between correlation-estimated 20% (hot fluid: 15%; cold 18%). These findings offer essential theoretical insights practical guidance for optimizing ensuring stable operation waste-heat recovery systems.
