Synthesis of heat‐integrated thermally coupled nonsharp distillation using self‐adaptive spherical search

AIChE Journal, EarlyView.
Abstract Although thermally coupled distillation (TCD) exhibits strong energy efficiency, the possibility of utility cost savings remains debatable. TCD designs that do not consider vapor transport can underestimate costs, making section rearrangement crucial to find more operable configurations.

Tailoring bubble size through acoustic‐assisted microbubble generation

AIChE Journal, EarlyView.
Abstract Various bubble generation methods have been developed to produce microbubbles, but current techniques are inadequate for meeting industrial demands for controlling the size of microbubbles accurately. This study aimed to investigate acoustic bubble generation as a potential solution to the demand.

Probabilistic approaches in civil engineering: generation of random fields and structural identification with genetic algorithms

, 2008
The inherent stochastic character of most of the physical quantities involved in engineering models has led to an always increasing interest for probabilistic analysis. Many approaches to stochastic analysis have been proposed. However, it is widely acknowledged that the only universal method available to solve accurately any kind of stochastic ...

A novel methodology to determine the safe operating regime for an offshore wind‐integrated electrolysis system

AIChE Journal, EarlyView.
Abstract The offshore wind‐integrated hydrogen production system is a novel approach to producing green energy carriers and chemicals. Even with the significant environmental benefits of this approach, there are major questions and concerns regarding its safety.

Large-scale modular and uniformly thick origami-inspired adaptable and load-carrying structures

Nature Communications
Existing Civil Engineering structures have limited capability to adapt their configurations for new functions, non-stationary environments, or future reuse. Although origami principles provide capabilities of dense packaging and reconfiguration, existing

Solution of boundary value problems for batteries: Operator‐theoretic methods

AIChE Journal, EarlyView.
Abstract Batteries with porous electrodes of negligible ionic and electronic conduction resistance are modeled with reaction‐diffusion equations in multilayered media. The classical separation of variables becomes inapplicable to battery problems because of nonlinearities in reaction rates and constraints of imposed current. A linear operator‐theoretic

The transition from the fixed to the fluidized state of well‐mixed binary‐solid mixtures in a liquid upflow

AIChE Journal, EarlyView.
Abstract In this work, an investigation of the transition from fixed to fluidized state of initially homogeneous binary‐solid mixtures due to an upward liquid flux was carried out. Like for analogous gas systems, it was confirmed that the full transition occurs over a range of fluid velocities, from the initial to the final fluidization velocity. Based

Optimal reactive operation of general topology supply chain and manufacturing networks under disruptions

AIChE Journal, EarlyView.
Abstract Supply and manufacturing networks in the chemical industry involve diverse processing steps across different locations, rendering their operation vulnerable to disruptions from unplanned events. Optimal responses should consider factors such as product allocation, delayed shipments, and price renegotiation, among other factors. In such context,

Hindered cracking in colloidal suspension coatings via evaporation‐driven lyotropic liquid crystals

AIChE Journal, EarlyView.
Abstract We demonstrate that lyotropic liquid crystalline (LC) phases, formed by the molecular interactions between 1‐glyceryl monooleyl ether (GME) and water, offer new pathways for producing crack‐free particulate films from colloidal suspensions. Drying experiments on titanium dioxide‐ethanol‐water‐GME suspension systems revealed a 15‐fold increase ...

Reinforcement learning for optimal control of stochastic nonlinear systems

AIChE Journal, EarlyView.
Abstract A reinforcement learning (RL) approach is developed in this work for nonlinear systems under stochastic uncertainty. A stochastic control Lyapunov function (SCLF) candidate is first constructed using neural networks (NNs) as an approximator to the value function, and then a control policy designed using this SCLF is developed to ensure the ...
