A trigenerative compressed air energy storage system (CAES) integrating vortex tubes is investigated numerically. In this work, the system is sized according to the electrical power required for the community of Aupaluk in Nunavik (QC). The vortex tube parameters are optimized using a genetic algorithm to maximize the electrical efficiency of the system and the reduction in carbon dioxide emissions. The proposed system increases both the electrical efficiency and the reduction in carbon dioxide emissions when compared to the same system using a throttling valve in the discharging process. Details on the pressure and temperature levels at each step of the system are provided for the optimal solution. Finally, vortex tubes may generate liquid carbon dioxide from atmospheric air in CAES using high storage pressure. This new quadrigeneration CAES is one promising way to address the problem of climate change.Index Terms-Compressed-air energy storage system, Ranque-Hilsch vortex tube, thermodynamic model, multiobjective optimization.

“…Besides, the heating effect of VT can be employed to elevate relatively lower temperatures to a more usable level. Based on these advantages, the vortex tube has been employed in versatile applications across diverse fields including thermodynamic systems, 1 gas and particle separations, 2 machining and metalworking, 3 and combined systems 4 . In these applications, various working fluids have been considered and applied, including hydrogen, 5 supercritical carbon dioxide, 6 mixture of hydrocarbon components and nitrogen, 7 and natural gas 8 and hydrocarbon (Cyclohexane–N‐Pentane) 9 (as shown in Figure 1).…”

With the widespread application of vortex tube in various fields, it becomes essential to quantitatively explore the separation effect of different fluids (natural fluids, hydrocarbons, etc.) within the vortex tube and to promote its utilization. A new approach has been developed in this study to establish quantitative models for predicting the thermal effects of different fluids in a vortex tube. These models are based on both the macro properties of the working fluid and micro molecular descriptor through a molecular scale. A dataset of 11 numerical simulation results of hydrocarbons and hydrofluorocarbons refrigerants is employed. Three operating conditions, 10 property parameters, and 115 molecular descriptors are screened and identified using random forest feature analysis. Two types of models (micro and macro) have been developed by employing artificial neural network (ANN) modeling techniques. In the result, four key influencing fluid property parameters (the specific heat ratio γ, the multiplication of heat capacity and the molar weight cp·M, the kinematic viscosity ν, and the thermal conductivity λ) and nine molecular descriptors in affecting the thermal effect are identified and respectively chosen as the input in the macro and the micro ANN model establishment. Both types of developed models show a high correlation coefficient (R > .999) and a comparatively low mean square error (MSE). When R600 is employed in the validation, most of the relative error is less than 10%, suggesting both types of models can work effectively in predicting the thermal effect for other fluid. The findings contribute to a deeper understanding of the thermodynamic effect of vortex tubes and provide a valuable tool for selecting and optimizing working fluids in various applications.

“…Tool wear and surface roughness were reduced in NGMQL + RHVT regime compared to others. Zhang et al 22 discussed the energy separation, mass separation, cooling, and heating performance of the vortex tube with different working fluids such as air, N 2 , Ar, and CO 2 . The effect of different properties such as thermal conductivity, molecular weight, thermal diffusivity, and specific heat capacity of pure gas fluids on the performance of the vortex tube was reviewed.…”

Dual nozzle vortex tube cooling system (VTCS) is developed to improve the machinability of Ti-6Al-4V where cold-compressed CO2 gas is used as a coolant. The cooling effect is produced by the process of energy separation in the vortex tube and the coolant is supplied into the machining zone to remove the generated heat in machining. In this study, the responses such as cutting force (Fz), cutting temperature (Tm), and surface roughness (Ra) are analyzed by considering coolant inlet pressure, cold fraction, and nozzle diameter as input variables. Further optimization is performed for the input variables using the genetic algorithm technique, and the results at optimum conditions are compared with those of dry cutting. From the results, lower cutting force is observed at lower coolant pressure and cold fraction and higher nozzle diameter. The cutting temperature is minimized by increasing coolant pressure and cold fraction and by decreasing nozzle diameter. A better surface finish is observed at high coolant pressure and cold fraction and lower nozzle diameters. It is observed from the response surface method (RSM) that the coolant pressure is most significantly affecting all the responses. At optimum conditions, the cutting temperature and surface roughness are 35.6% and 66.14%, respectively, lower than dry cutting due to the effective cooling and lubricating action of the CO2 gas, whereas cutting force observed under the VTCS is 18.6% higher than that of dry cutting because of the impulse force of the coolant VTCS and thermal softening of the workpiece in dry cutting.
