A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios
Chemie Ingenieur Technik, EarlyView.A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

Research on Controlled Hydrostatic Bearing
Transactions of the Japan Society of Mechanical Engineers, 1964 For controlled hydrostatic bearings having variable restrictions, it is possible to make their static stiffness increase greatly by means of the automatic regulation of recess pressure; namely the recess pressure controlled by a spool valve rises rapidly according to the displacement of journal or shaft, thus the bearings possess very high load ...

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Optimization of Hydrostatic Thrust Bearings
Journal of the Japan Society of Precision Engineering, 1978 In this paper, the theoretical studies on the optimization of the operating condition of the hydrostatic thrust bearings are presented. Total amount of power consumption is treated as an objective function, while the bearing clearance, static stiffness, damping ratio of the bearing, lubricant viscosity and the initial lift up pressure are considered as

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
