Enhanced heat transfer of variable pitch helical baffle plate orifice plate-type heater for downhole in situ oil shale extraction

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(5)

Published: May 1, 2025

This study proposes a variable pitch helical baffle plate orifice plate-type heater model to enhance heat transfer performance. Numerical simulations were conducted using Fluent analyze the and flow characteristics of heater, with focus on determining effects varying efficiency. research examines coefficient h, average wall temperature T, difference ΔT under different decreasing intervals Δx. The results indicate that h decreases continuously process, regardless whether is adjusted. Furthermore, larger interval Δx leads slower reduction in coefficient. T heating plates surface both decrease increasing Specifically, when = 20 mm, 2.36% lower, reduces by 9.13%–10.42% compared 0 mm. For best overall performance, 5 heater's evaluation index h/ΔP1/3 achieves optimal values, 2.94%–4.02% configuration offers most effective regulation.

Which Factors Are More Important in Land Consolidation Block Planning? An Analytic Hierarchy Process Approach for Prioritization

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 2314 - 2314

Published: March 6, 2025

Land consolidation is a comprehensive and challenging process in which block boundaries integrate parcels within natural infrastructural such as roads, irrigation systems, drainage networks, acting core framework. Effective design of critical importance, it affects the long-term usability productivity agricultural parcels. In this study, criteria effective planning were determined using Analytic Hierarchy Process (AHP), an attempt was made to determine priority order criteria. The affecting study land slope topography, soil properties fertility, climatic conditions, water resources facilities, current ownership structure (shareholding), road transportation, environmental ecological factors, social economic plant species activities, infrastructure technological fixed parcel structure, existence projects or be by investor institutions organizations. It that most important these “existence facilities” criterion. Determining used also provides opportunity use obtained results GIS.

Combined Framework for Teaching Quality Evaluation of Online English Courses of Vocational Colleges Under Interval Neutrosophic Sets

International Journal of Information System Modeling and Design, Journal Year: 2025, Volume and Issue: 16(1), P. 1 - 22

Published: May 2, 2025

The evaluation of teaching quality in vocational college English online courses is crucial. It monitors the process, ensures objectives are met, and improves course quality. Flexible methods comprehensively reflect outcomes, making a scientific system essential for improvement. colleges multiple-attribute group decision-making (MAGDM). Recently, LogTODIM approach MACONT was constructed to put forward MAGDM. interval neutrosophic sets (INSs) as tool managing fuzzy data during colleges. In this work, number LogTODIM-MACONT (INN-LogTODIM-MACONT) MAGDM under INSs. Ultimately, numerical analysis validate proposed approach.
