Numerical schemes for a moving-boundary convection-diffusion-reaction model of sequencing batch reactors
Raimund Bürger, Julio Careaga, Stefan Diehl +1
Sequencing batch reactors (SBRs) are devices widely used in wastewater treatment, chemical engineering, and other areas. They allow for the sedimentation and compression of solid p…
A model of reactive settling of activated sludge: comparison with experimental data
Raimund Bürger, Julio Careaga, Stefan Diehl +1
A non-negligible part of the biological reactions in the activated sludge process for treatment of wastewater takes place in secondary settling tanks that follow biological reactor…
A degenerating convection-diffusion system modelling froth flotation with drainage
Raimund Bürger, Stefan Diehl, M. Carmen Martí +1
Froth flotation is a common unit operation used in mineral processing. It serves to separate valuable mineral particles from worthless gangue particles in finely ground ores. The v…
A moving-boundary model of reactive settling in wastewater treatment. Part 2: Numerical scheme
Raimund Bürger, Julio Careaga, Stefan Diehl +1
A numerical scheme is proposed for the simulation of reactive settling in sequencing batch reactors (SBRs) in wastewater treatment plants. Reactive settling is the process of sedim…
A moving-boundary model of reactive settling in wastewater treatment. Part 1: Governing equations
Raimund Bürger, Julio Careaga, Stefan Diehl +1
Reactive settling is the process of sedimentation of small solid particles in a fluid with simultaneous reactions between the components of the solid and liquid phases. This proces…
A method-of-lines formulation for a model of reactive settling in tanks with varying cross-sectional area
Raimund Bürger, Julio Careaga, Stefan Diehl
Reactive settling denotes the process of sedimentation of small solid particles dispersed in a viscous fluid with simultaneous reactions between the components that constitute the…
Efficient simulations of tubulin-driven axonal growth
Stefan Diehl, Erik Henningsson, Anders Heyden
This work concerns efficient and reliable numerical simulations of the dynamic behaviour of a moving-boundary model for tubulin-driven axonal growth. The model is nonlinear and con…
A one-dimensional moving-boundary model for tubulin-driven axonal growth
S. Diehl, E. Henningsson, A. Heyden +1
A one-dimensional continuum-mechanical model of axonal elongation due to assembly of tubulin dimers in the growth cone is presented. The conservation of mass leads to a coupled sys…
