Optimization of a double sided centrifugal pump
Centrifugal pumps are widely used in industrial applications. Compared to single-entry centrifugal pumps, double-sided pumps allow transportation of greater flow rates due to smaller proneness to cavitation, and offer counter-balancing of axial hydraulic forces due to double-entry design. In turbomachines, usually multiple objectives have to be optimized.
Minimization of the Environmental Emissions of Closed-Loop Supply Chains A case study of returnable transport assets management
A closed-loop supply chain (CLSC) is a system where the forward and reverse flows of items occur and should be managed simultaneously. The proper management of a CLSC requires the design, control and operation of the system to maximize value creation over the entire life cycle of a product, with dynamic recovery of value from different types and volumes of returned items. This aim of this research is to evaluate and minimize the environmental impact of an existing CLSC.
Energy and daylighting optimization for an office with fixed and movable shading devices
In this paper, external fixed shading device geometry is optimized in order to reduce the overall energy consumption in an office room provided with an extensive glazing and moveable Venetian blinds. The optimizer modeFRONTIER drives the optimization using DAYSIM for internal illuminance and lighting electrical loads computation and ESP-r for building energy simulation. Here both the FAST and NSGA II genetic algorithms have been applied using the simplified approach of DAYSIM.
Parametric Optimization of a Ladder Vehicle Chassis
In this optimization process, modeling and simulation are done by coupling softwares ANSYS and modeFRONTIER. The objective is the reduction of dimensions of a vehicle ladder chassis, using a Cargo C-816 model, conceptually compound by two stringers and five traverse beams that connect them. FEA and concepts of manufacturing processes and mechanic of materials are used to certify the structure’s integrity after the initial volume reduction.
