A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

Chemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.

A Hybrid Algorithm Modeling on Test-Bench Data for Light-Duty Afterburning Turbojet Engine

Aerospace
For highly maneuverable aircraft, the afterburning engine serves as a core and critical component. Due to the complex structure of the afterburner and the strong coupling among parameters, mechanism-based modeling of afterburning engines remains ...

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Effect of Dependent Scattering on Light Absorption in Highly Scattering Random Media

, 2017
The approximate nature of radiative transfer equation (RTE) leads to a bunch of considerations on the effect of "dependent scattering" in random media, especially particulate media composed of discrete scatterers, in the last a few decades, which usually

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

Statistical framework for condensation frosting incipience on smooth and nanostructured surfaces

Droplet, EarlyView.
A statistical framework for frost incipience that considers the effect of surface wettability and captures the stochastic nature of both nucleation dynamics for condensation and droplet growth during the subsequent freezing process. Abstract Frost and ice formation on a solid surface is governed by nanoscale liquid‒solid intermolecular interactions ...

Ground Servoelasticity Test and Analysis of UAVs With Large Aspect Ratio and Joined-Wing Layout

IEEE Access
Unmanned aerial vehicles (UAVs) with an ultra-large aspect ratio and a joined-wing configuration exhibit characteristics such as minimal mass, remarkable flexibility, and a unified wing structure, thereby presenting a significant challenge in accurately ...

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

Deep Underground Science and Engineering, EarlyView.
The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in
