Neural networks for small scale ORC optimization
This study concerns a thermodynamic and technical optimization of a small scale Organic Rankine Cycle system for waste heat
recovery applications. An Artificial Neural Network (ANN) has been used to develop a thermodynamic model to be used for
the maximization of the production of power while keeping the size of the heat exchangers and hence the cost of the plant at its
minimum. R1234yf has been selected as the working fluid. The results show that the use of ANN is promising in solving complex
nonlinear optimization problems that arise in the field of thermodynamics
Natural flow patterns and structured people dynamics: a constructal view
Constructal theory that has been successfully applied to planetary circulations and
climate and to river basin morphology is shown to provide a useful framework
for describing flows of people. We showed here, with simple examples, that
intuitive rules of traffic organization can be anticipated based on principle, i.e.,
based on the Constructal Law. In addition, and similarly to the case of flows
of inanimate matter, in the case of flows of people, flow patterns emerge as
a necessary consequence of reduction of global flow resistances. These flow
patterns point to decreasing resistivity to flows of people and commodities.
Pathway length varies inversely with resistivity while pathway number increases
with resistivity
Optimization of the logistics of agricultural biogas plants = Optimalisatie van de logistiek bij mestvergistingsinstallaties
Within the framework of the EU-AGRO-BIOGAS project, the optimisation model Bioloco has been adapted for the application on biogas plants and was applied on a Dutch example case
