Drag force correlations and effect of charged particles on drag force for particle-laden flows
, 2022 Hesaplamalı Akışkanlar Dinamiği (HAD) aracı olan pafiX (patlama korumasında parçacık akışı simülasyonu), parçacık yüklü akışların elektrostatik yüklenmesi olayını modellemeye odaklanır. İki fazlı akışların HAD simülasyonlarında, parçacık dinamiklerini tahmin etmek için doğru sürükleme kuvveti modellemesi esastır. Mevcut sürükleme kuvveti korelasyonları

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators
Advanced Robotics Research, EarlyView.Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

Design of Hydraulic Induced Bidirectional Coupling Coiled Tubing Drag Reducer
Shiyou jixie, 2020 The low rigidity of the coiled tubing makes it easy to buckle during running or drilling, which leads to increased drag and even locking. To address the problem, based on the Coanda effect and the Carmen vortex effect, a hydraulically induced ...

Landslide Drag Forces on Pipelines
Soils and Foundations, 1991 ABSTRACT An experimental program was carried out to investigate the effect of landslide (or mudslide) velocity on the drag force applied by the sliding soil on a pipeline crossing the landslide area. Methods currently used in assessing drag forces are reviewed and compared to the experimental results.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...
