As results, inlet flow rate, inclination angle of wall and inlet design are proposed for optimum operational conditions.
The surface quality could be improved via optimization of nozzle outlet geometry, gas flow rate, inclination angle of gas tube, and distance between the nozzle and laser beam.
Maps of efficiency of gas separation were plotted and showed that liquid flow rate, inclination angle and pressure difference between casing and production pipe outlet are the main variables related to the gas separation phenomenon.
The model is conducted to determine the effects of liquid flow rate, air injection rate, annulus inclination angle, elevated temperature and pressure on the cuttings transport efficiency.
Test results show that the load and energy dissipation capacities for straight smooth fibers generally increase with loading rate and inclination angle up to 45°.
The coalescence rate, defined as the decrease in the ensemble size, becomes almost negligible at x/D>60, independent of pipe diameter, flow rates and inclination angle.
The shape of the gas slug in tube is influenced by the diameter of tube, the flow rate, and the inclination angle.
Also, the nucleation rate at an inclination angle of 90° is higher than that of 45° especially for the growth temperature of 600°C by comparing the grown structures on ML graphene.
The process parameters were optimized by using Response Surface Methodology RS M in Design Expert software to attain maximum thermal performance.The maximum heat transfer coefficient of 6874.48 was2K was obtained under the optimized conditions of 0.03 kg/s of mass flow rate, 67.5o of inclination angle and 213 W of heat input.
The model is a modified diffusion limited aggregation model, and uses essential properties governing front stability as model input: DNAPL water viscosity differences, DNAPL water density differences, intrinsic permeability of the porous media, flow rate, and the inclination angle of the porous media from the horizontal.
In a differentially heated inclined enclosure, the heat transfer rate increases as the inclination angle increases up to an optimum inclination angle (45° for Ra = 104, 30° for Ra = 105 and 106), beyond which the heat transfer rate decreases, e.g., [10, 12, 13].
