Miguel, Department of Physics, School of Sciences and Technology, University of Évora, Rua Romao Ramalho 59, 7000-671 Évora, Portugal e-mail: [email protected] The occurrence of configuration (design, shape, structure, rhythm) is a universal phenomenon that occurs in every flow system. Dendritic configuration (or tree-shaped configurations) is ubiquitous in nature and li...

We describe the creation of monodisperse microbeads of polydimethylsiloxane (PDMS) via a microfluidic approach. Using a flow-focusing configuration, a PDMS precursor solution is dispersed into microdroplets within an aqueous continuous phase. These droplets are collected and thermally cured off-chip into solid microbeads. Our microfluidic technique allows for direct integration of payloads into...

We consider the problem of automatically mapping computation-intensive loop nests onto FPGA hardware. The regular cell array structure of these chips reflects the parallelism in regular loop-like computations. Furthermore, the flexibility of FPGAs allows the cost-effective implementation of reconfigurable high performance processor arrays. So far, there exists no continuous design flow that all...

Macro-mixing effects in batch and semi-batch reactors are investigated by constructing 3-dimensional models using a network of zones (NoZ) discretisation. System dynamics including volume changes due to continuous feeding are successfully predicted. Detailed flow fields are calculated from phenomenological correlations which include parameters such as reactor size and configuration, impeller ty...

Tip leakage loss introduces major part of losses of the rotor in axial gas turbines. Therefore, the rotor blade tip has a considerable effect on rotor efficiency. To understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). Various blade tip configurations s...

The impact of adding a modified Ludzack–Ettinger (MLE) configuration with Nitrate Recycle (NRCY) on continuous-flow aerobic granulation has yet to be explored. potential negative effects MLE sludge densification include that: (1) bioflocs brought by NRCY could compete granules in feast zones; and (2) carbon addition anoxic zones increase the system organic loading rates lead higher feast-to-fam...
