| 1 | Modelling the bed characteristics in fluidised-beds for top-spray coating processes显示文摘A particle sub-model describing the bed characteristics of a bubbling fluidised bed is presented.Atomisation air,applied at high pressures via a nozzle positioned above the bed for spray formation,is incorporated in the model since its presence has a profound influence on the bed characteristics,though the spray itself is not yet considered.A particle sub-model is developed using well-known empirical relations for particle drag force,bubble growth and velocity and particle distribution above the fluidised-bed surface.Simple but effective assumptions and abstractions were made concerning bubble distribution,particle ejection at the bed surface and the behaviour of atomisation air flow upon impacting the surface of a bubbling fluidised bed.The model was shown to be capable of predicting the fluidised bed characteristics in terms of bed heights,voidage distributions and solids volume fractions with good accuracy in less than 5 min of calculation time on a regular desktop PC.It is therefore suitable for incorporation into general process control models aimed at dynamic control for process efficiency and product quality in top-spray fluidised bed coating processes. | Mike Vanderroost Frederik Ronsse Koen Dewettinck Jan G.Pieters | 2012 | Particuology2012，10，6： | 2 |

| 6 | Modelling overall particle motion in fluidised beds for top-spray coating processes显示文摘A mathematical model predicting the overall particle motion in liquid-sprayed gas-solid fluidised beds has been developed.The proposed model is a superposition of bubble-induced particle motion and particle random walk.The model was validated using experimental particle residence times from literature.Good agreement between experimental and model-predicted residence times was obtained for those cases where atomisation air was absent and on the condition of the inclusion of a so-called 'dead zone'.The 'dead zone',being a region of stagnant particles in the annular bottom part of the bed,has also been previously reported in literature.In case atomisation air was present,a less favourable agreement was seen between the model and the experiment.As the atomisation air has been shown to significantly alter the ejection distance of particles in the freeboard,recalibration of the ejection height parameter has been demonstrated to obtain an acceptable agreement between model-predicted and experimental data. | Mike Vanderroost Frederik Ronsse Koen Dewettinck Jan G.Pietersa | 2013 | Particuology2013，11，5： | 1 |
| 7 | Biochar from sawmill residues:characterization and evaluation for its potential use in the horticultural growing media显示文摘Peat remains the primary constituent of horticultural growing media in professional use.However,use of peat in horticultural growing media results in greenhouse gas emissions and biodiversity loss due to excavation of natural peatlands.Biochar is gaining attention as a sustainable alternative to peat use in horticulture.This study examined the potential of biochar produced from a particular type of sawmill residue,as a partial replacement for peat in horticultural growing media.Five treatments including peat only,biochar only,biochar and peat in 1:1,1:3,and 3:1(V/V)ratios were assessed.The addition of biochar into growing media increased the pH and EC of the medium.However,physical properties(air-filled porosity and water holding capacity)were negatively affected with the increase in biochar content in the medium.According to the germination test results,biochar significantly improved germination and the shoot and root length of germinated seeds of cress,lettuce and tomato when compared to peat-only and biochar-only treatments.The inclusion of biochar in 25-50%volume ratio improved plant growth parameters compared to peat-only and biochar-only media.Results obtained from this study suggest that sawmill residue offers great potential as a feedstock for biochar production and inclusion of biochar has positive effects on seed germination and plant growth that might compete with modified peat. | Dilani Rathnayake Hamish Creber Reinhart Van Poucke Saran Sohi Erik Meers Ondřej Mašek Frederik Ronsse | 2021 | Biochar2021，3，2： | 0 |
