| 2 | Brillouin-scattering-induced transparency enabled reconfigurable sensing of RF signals显示文摘Real-time spectrum sensing is essential to enable dynamic and rapid spectrum sharing of unused frequencies to cater the substantial demands of new wireless services deploying the existing RF bands.In this paper,we present a novel,real-time spectrum sensing approach for widely used RF signals based on Brillouin-scattering-induced transparency(BIT).A temporal discrimination of multi-channel input frequencies is achieved through the group delay tuning by BIT.By tuning the pump power and frequency,the proposed technique is fully reconfigurable and viable for a broad range of spectrum sensing.Several experimental illustrations of the time domain sensing are presented for two-tone channels with 0.9,1.8,and 5 GHz frequencies to detect the unused spectrum within 3 G,4 G,and 5 G signals. | JAFFAR KADUM RANJAN DAS ARIJIT MISRA THOMAS SCHNEIDER | 2021 | Photonics Research2021，9，8： | 0 |

| 4 | Evaluation of Shell and Tube Heat Exchanger Performance by Using ZnO/Water Nanofluids显示文摘To examine and investigate the impact of nanofluid on heat exchanger performance,including the total heat transfer,the effect of friction factor,the average Nusselt number,and the thermal efficiency,the output heat transfers of a shell and tube heat exchanger using ZnO nanoparticles suspended in water has been conducted numerically.The governing equations were solved using finite volume techniques and CFD simulations with ANSYS/FLUENT Solver 2021.The nanoparticles volume fractions adopted are 0.2%and 0.35%that used in numerical computations under 200 to 1400 Reynolds numbers range.The increasing of temperature is approximately 13%from the bottom to the top of heat exchanger,while the maximum enhancement of Nusselt number is about 10%,19%for volume fractions 0.2%and 0.35%respectively.The elevated values of the friction factor at the volumetric ratios of 0.2%and 0.35%are 0.25%and 0.47%respectively.The findings demonstrate that the performance efficiency of shell and tube heat exchanger is enhanced due to the increase in Nusselt number. | Hussein Hayder Mohammed Ali Adnan M Hussein Kadum Mohammed Hussain Allami Barhm Mohamad | 2023 | Journal of Harbin Institute of Technology(New Series)2023，30，6： | 0 |
