TL;DR: In this article, experimental measurements of the volumetric liquid mass transfer and bubble size distribution in a vertically oriented semi-batch gas-liquid Taylor-Couette vortex reactor with radius ratio η = ǫ/r/rǫ −075 and aspect ratio Γ −= h/(ro −− �) −40 were performed, and the results were presented for axial and azimuthal Reynolds number ranges of Rea −119 −143 and ReΘ −= 0 −35 −×104, respectively.

TL;DR: In this paper, a standing wave thermoacoustic engine is simulated with linear thermo-acoustics and the authors show that an appropriate accretion of the resonance tube length may lead to a decrease of the working frequency and an increase of the pressure amplitude.

TL;DR: It is shown that algal growth rate in Taylor vortex reactors is not limited by fluid mixing or interphase mass transfer, and therefore the observed biomass productivity improvements are likely attributable to improved light utilization efficiency.

TL;DR: In this paper, an Euler-Euler multiphase CFD model is proposed for continuous fast pyrolysis of biomass in a fluidized-bed reactor, where variable particle porosity is used to account for the evolution of the particle's physical properties, and particle kinetic processes and their interactions with the reactive gas phase are modeled with a multi-fluid description derived from the kinetic theory of granular flows.
Abstract: In this work, an Euler–Euler multiphase CFD model is proposed for continuous fast pyrolysis of biomass in a fluidized-bed reactor. In the model, a lumped, multi-component, multi-stage kinetic model is applied to describe the pyrolysis of a biomass particle. Variable particle porosity is used to account for the evolution of the particle's physical properties. Biomass is modeled as a composite of three reference components: cellulose, hemicellulose, and lignin. Pyrolysis products are categorized into three groups: gas, tar vapor (bio-oil), and solid char. The particle kinetic processes and their interactions with the reactive gas phase are modeled with a multi-fluid description derived from the kinetic theory of granular flows. A time-splitting approach is applied to decouple the convection and reaction calculations using a synchronized time step. The CFD model is employed to study the fast pyrolysis of both cellulose and bagasse in a lab-scale fluidized-bed reactor. The dynamics, particle heating, reaction of the biomass phase, char formation, elutriation, and spatial distribution of tar and gas inside the reactor are investigated. The yields of tar, gas, and char are also discussed.

TL;DR: It is found that Monod model's shortcoming in internal substrate utilization is well fixed by modified Droop model, and the flat plate PBs are applicable in PB-based architectures and infrastructures indicating an encouraging revenue-raising potential.
