Configuration of the Power Reflux Hydro-Mechanical Transmission System

Actuators
The hydro-mechanical transmission system (HMTS) operates either in power split transmission mode (PSTM) or power reflux transmission mode (PRTM). Although PRTM is often ignored as a transition mode, this study reveals that the HMTS operating in the PRTM ...

Estimating Transmissivity in One‐Dimensional Heterogeneous Aquifers With Groundwater Head Data: From Time or Frequency Perspectives

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Time series of groundwater head in a semi‐infinite, one‐dimensional confined aquifer due to variable boundary forcing can be decomposed into two signals: head rise from a sudden boundary increase, and head fluctuation from boundary sinusoidal changes.

Characterisation of Groundwater Flow in the Deltaic Aquifer‐Aquitard System

Hydrological Processes, Volume 39, Issue 9, September 2025.
This study employs a permanent multilevel groundwater monitoring system to capture high‐resolution, hourly groundwater level fluctuations in a deltaic basin, providing an unprecedented dataset for evaluating groundwater flow dynamics. Fractal behaviours are used to explore the deltaic groundwater flow system.

Monitoring Fracture Hydromechanical Evolution in the Lab and Field Using Unsupervised Metric Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Fractures evolve in time through thermal‐hydraulic‐mechanical‐chemical (THMC) processes that alter their long‐range hydraulic transport properties and modify subsurface behavior and activities. The location of subsurface fractures makes it necessary to use remote sensing techniques such as passive or active seismic monitoring for fracture ...

Kinematic analysis of double-flow hydromechanical transmissions

Traktory i sel hozmashiny, 2016
Double-flow hydromechanical transmissions become more and more widely used in designs of modern tractors and automobiles. Double-flow hydromechanical transmission includes a torque converter or a complex hydrodynamic transmission and a differential unit made in form of three-link differential device. The article discusses all of the 12 possible schemes

Development of 1D Hybrid Hydromechanical Models for Real‐Time Forecasting of Induced Seismicity Rate

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Hydraulic stimulations play an important role in Enhanced Geothermal Systems (EGS) by increasing the permeability of the host rock and facilitating more efficient fluid circulation and heat extraction. However, fluid injection operations are unavoidably accompanied by induced earthquakes.
