Evaluating the sensitivity of surrogate optimization target properties characterizing droplet formation, evaporation, and chemical reactions to biodiesel composition reduction

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Liquid fuels contain a large number of components. However, it is not computationally feasible to implement the detailed composition into numerical solvers in combustion chamber design. Surrogate mixtures are used to facilitate calculations, which can reproduce the fuel characteristics with fewer components providing reasonable accuracy ...

Uncertainty in inventories for life cycle assessment: State‐of‐the‐art, challenges, and new technologies

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Uncertainty is a critical factor that can hinder the quality and potential applications of life cycle assessment (LCA) results. A prominent source of uncertainty stems from the life cycle inventory (LCI) data. Various methodologies exist to estimate the uncertainty associated with LCI data, primarily based on the widely used structured ...

Investigation on the Calibration of Numerical Models for Cast Steel Replaceable Modular Yielding Links in Steel Eccentrically Braced Frames

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT A new generation of yielding links, referred to as cast steel replaceable modular yielding links (CMLs), was recently validated through extensive large‐scale testing, to enhance the seismic performance of steel eccentrically braced frames (EBFs). The effective use of CMLs relies on accurately evaluating the seismic response of the EBF systems,

Dynamic simulation of a peristaltic micropump considering coupled fluid flow and structural motion [PDF]

, 2007
This paper presents lumped-parameter simulation of dynamic characteristics of peristaltic micropumps. The pump consists of three pumping cells connected in series, each of which is equipped with a compliant diaphragm that is electrostatically actuated in

Modeling Nonlinear Cyclic Load–Deformation Response of Corrosion‐Damaged Reinforced Concrete Columns

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study presents a lumped plasticity modeling method for simulating the nonlinear load–deformation response of corroded reinforced concrete (RC) columns with rectangular and circular cross‐sections. The proposed modeling method utilizes an extended column database to enhance the robustness of the database and considers cyclic degradation ...
