| 1 | Euler-Euler CFD modeling of fluidized bed:Influence of specularity coefficient on hydrodynamic behavior显示文摘Euler-Euler two-fluid model is used to simulate the hydrodynamics of gas-solid flow in a bubbling fluidized bed with Geldert B particles where the solid property is calculated by applying the kinetic theory of granular flow(KTGF).Johnson and Jackson wall boundary condition is used for the particle phase,and different amount of slip between particle and wall is given by varying the specularity coefficient(φ) from0 to 1.The simulated particle velocity,granular temperature and particle volume fraction are compared to investigate the effect of different wall boundary conditions on the hydrodynamic behavior.Some of the results are also compared with the available experimental data from the literature.It was found that the model predictions are sensitive to the specularity coefficient.The hydrodynamic behavior deviated significantly for φ = 0 and φ = 0.01 with maximum deviation found at φ = 0 i.e.free-slip condition.However,the overall bed height predicted by all the conditions is similar. | Chanchal Loha Himadri Chattopadhyay Pradip K.Chatterjee | 2013 | Particuology2013，11，6： | 7 |
| 2 | Effect of coefficient of restitution in Euler-Euler CFD simulation of fluidized-bed hydrodynamics显示文摘Collision between particles plays an important role in determining the hydrodynamic characteristics of gas-solid flow in a fluidized bed.In the present work,earlier work(Loha,Chattopadhyay.& Chatterjee,2013) was extended to study the effect of the elasticity of particle collision on the hydrodynamic behavior of a bubbling fluidized bed filled with 530-μm particles.The Eulerian-Eulerian two-fluid model was used to simulate the hydrodynamics of the bubbling fluidized bed.where the solid-phase properties were calculated by applying the kinetic theory of granular flow.To investigate the effect of the elasticity of particle collision,different values of the coefficient of restitution were applied in the simulation and their effects were studied in detail.Simulations were performed for two different solid-phase wall boundary conditions.No bubble formation was observed for perfectly elastic collision.The bubble formation started as soon as the coefficient of restitution was set below 1.0,and the space occupied by bubbles in the bed increased with a decrease in the coefficient of restitution.Simulation results were also compared with experimental data available in the literature,and good agreement was found for coefficients of restitution of 0.95 and 0.99. | Chanchal Loha Himadri Chattopadhyay Pradip K.Chatterjee | 2014 | Particuology2014，12，4： | 6 |
| 3 | Role of the CXCR4-SDF1-HMGB1 pathway in the directional migration of cells and regeneration of affected organs显示文摘In recent years,several studies have reported positive outcomes of cell-based therapies despite insufficient engraftment of transplanted cells.These findings have created a huge interest in the regenerative potential of paracrine factors released from transplanted stem or progenitor cells.Interestingly,this notion has also led scientists to question the role of proteins in the secretome produced by cells,tissues or organisms under certain conditions or at a particular time of regenerative therapy.Further studies have revealed that the secretomes derived from different cell types contain paracrine factors that could help to prevent apoptosis and induce proliferation of cells residing within the tissues of affected organs.This could also facilitate the migration of immune,progenitor and stem cells within the body to the site of inflammation.Of these different paracrine factors present within the secretome,researchers have given proper consideration to stromal cell-derived factor-1(SDF1)that plays a vital role in tissue-specific migration of the cells needed for regeneration.Recently researchers recognized that SDF1 could facilitate site-specific migration of cells by regulating SDF1-CXCR4 and/or HMGB1-SDF1-CXCR4 pathways which is vital for tissue regeneration.Hence in this study,we have attempted to describe the role of different types of cells within the body in facilitating regeneration while emphasizing the HMGB1-SDF1-CXCR4 pathway that orchestrates the migration of cells to the site where regeneration is needed. | Nazmul Haque Ismail M Fareez Liew Fong Fong Chanchal Mandal Noor Hayaty Abu Kasim Kranthi RajaKacharaju Pratiwi Soesilawati | 2020 | World Journal of Stem Cells2020，12，9： | 3 |

| 18 | A fuzzy logic algorithm derived mechatronic concept prototype for crop damage avoidance during eco-friendly eradication of intra-row weeds显示文摘Crop damage during the intra-row weed eradiation is one of the biggest challenges in intercultural agricultural operations.Several available mechanical systems provide effective weeding but result in excess crop damage.On the other hand,chemical based systems have been raising serious environmental and food concerns.This study presents development of a cost-effectivemechatronic prototype for intra-rowweeding operation.The primary focus was on incurring minimal crop damage.The system integrates time of flight and inductive sensing into fuzzy logic algorithm for electronic control of a four-bar linkage mechanism(FBLM).The crank of FBLM was connected to the vertical rotary weed control shaft with weeding blades.The crop sensing triggers the electronic control to laterally shift the control shaft away from crop,proportional to the forward speed and soil conditions.The developed algorithm incorporates varied conditions of soil,forward speed,and plant spacing to calculate dynamic lateral shift speed(SRPM).The prototype was evaluated to determine the relationships between the operating conditions and electronic control parameters.Moreover,the plant damage was assessed under varied conditions of plant spacing,forward speeds,soil cone index,operational depth and electronic control parameters.The derived SRPM was established as the ultimate governing factor for avoiding crop damage that varied significantlywith electronic response time and soil strength(P<0.05).Plant damage increased significantly under higher forward speeds and lower plant spacing(P<0.05).Preliminary field evaluation of the developed prototype showed a significant potential of this system for effective control on weeds(>65%)and crop damage(<25%). | Satya Prakash Kumar V.K.Tewari Abhilash K.Chandel C.R.Mehta Brajesh Nare C.R.Chethan Kaustubh Mundhada Prateek Shrivastava Chanchal Gupta Smrutilipi Hota | 2020 | Artificial Intelligence in Agriculture2020，，1： | 1 |
