Analysis and multi-criteria design optimization of geometric characteristics of grooved micromixer
Cortes Quiroz, Cesar; Azarbadegan, Alireza; Zangeneh, Mehrdad; Goto, Akira (2010-06-15)Computational fluids dynamics (CFDs) and numerical optimization techniques are applied in an integrated methodology to explore the effects of different geometric characteristics on fluid mixing in a staggered herringbone ... -
Analysis and optimization of a passive micromixer with curved-shaped baffles for efficient mixing with low pressure loss in continuous flow
Cortes Quiroz, Cesar; Azarbadegan, Alireza; Moeendarbary, Emadaldin; Zangeneh, Mehrdad (American Society of Mechanical Engineers (ASME), 2011)Numerical simulations and an optimization method are used to study the design of a planar T-micromixer with curved-shaped baffles in the mixing channel. The mixing efficiency and the pressure loss in the mixing channel ... -
Analysis of double-chamber parallel valveless micropumps
Azarbadegan, A.; Cortes Quiroz, Cesar; Eames, I.; Zangeneh, M. (2010-08)The characteristics of a double-chamber valveless parallel micropump are analysed using a one-dimensional non-linear model. The relationships between the mean volume flux, pressure difference and (measurable) characteristics ... -
Characterization and optimization of a three dimensional T-type micromixer for convective mixing enhancement with reduced pressure loss
Cortes Quiroz, Cesar; Azarbadegan, Alireza; Zangeneh, Mehrdad (American Society of Mechanical Engineers (ASME), 2011)Numerical simulations and experiments are used to evaluate the flow and mixing characteristics of a proposed convective 3-D T-type micromixer. The study presents a parametric study and performance optimization of this ... -
Combination rules for multi-chamber valveless micropumps
Azarbadegan, Alireza; Eames, Ian; Wojcik, Adam; Cortes Quiroz, Cesar; Suen, William (2013-10)The general design rules indicate that when identical macroscale pumps (each with a maximum flowrate Qm, and maximum pressure drop ΔPmax) are combined in series the maximum flowrate becomes Qm, but the maximum pressure is ... -
An efficient passive planar micromixer with fin-shaped baffles in the tee channel for wide Reynolds number flow range
Cortes Quiroz, Cesar; Azarbadegan, A.; Moeendarbary, E. (2010)A new design of a planar passive T-micromixer with fin-shaped baffles in the mixing channel is presented. The mixing efficiency and the level of pressure loss in the channel have been investigated by numerical simulations ... -
Investigation of Double-Chamber Series Valveless Micropump : An Analytical Approach
Azarbadegan, A.; Moeendarbary, E.; Cortes Quiroz, Cesar; Eames, I. (Institute of Electrical and Electronics Engineers (IEEE), 2010)We describe an analytical study of the characteristics of a double-chamber series valveless micropump using a one-dimensional non-linear model. We derive a closed-form expression for relationship between the mean volume ... -
A numerical study of the effects of wind acting in different directions on clad scaffolds erected around a low-rise building
Cortes Quiroz, Cesar; Irtaza, H.; Beale, R.G. (Civil-Comp Press, 2011)This paper presents the application of computational fluid dynamics on the analysis of the effects of wind loads on sheeted scaffold structures. This theoretical work has been validated against the experimental results ... -
On multi-objective optimization of geometry of staggered herringbone micromixer
Cortes Quiroz, Cesar; Zangeneh, Mehrdad; Goto, Akira (2009-07)A design methodology for micromixers is presented which systematically integrates computational fluid dynamics (CFD) with an optimization methodology based on the use of design of experiments (DOE), function approximation ... -
Optimization of diffuser/nozzle elements for rectification valveless micropumps
Azarbadegan, A.; Cortes Quiroz, Cesar; Moeendarbary, E.; Eames, Ian (American Society of Mechanical Engineers (ASME), 2011)There has been a growing interest in understanding the flow behaviour inside diffuser/nozzle elements in order to identify performance characteristics of these elements for micropump applications. Flat-walled diffuser/nozzle ...
