Abstract: A new variable water (VW) flow system for chilled water system application is presented. Design, operational, and control issues are discussed. Analytical models of pump power and evaporative ...

Abstract: There is no common agreement on the use of balance valves in the most popular variable water flow systems. A comprehensive theoretical analysis has been conducted to investigate the impacts ...

Abstract: This paper presents optimal outside air control schedules for an integrated air-handling unit system for large commercial buildings (OAHU). The schedules are developed using the geometric linear ...

Abstract: The constant-speed fan wastes fan energy and causes excessive noises in nonmakeup-air exhaust systems, where stack-exit velocity decreases proportionally to the laboratory exhaust airflow. A variable-frequency drive (VFD) ...

Abstract: The effect of three-dimensional defects such as voids and inclusions on the sliding contact subsurface stress distribution and fatigue limit is investigated. Three-dimensional finite-infinite boundary ...

Abstract: A new concept of controlling tool geometry for in-process chatter suppression is quantitatively evaluated. Experimentally derived relationships between machining stability and tool geometry, namely, ...

Abstract: Recovery of hydrofluoric acid (HF) from waste semiconductor acid solution by ion exchange was investigated. Strong base anionic and strong acid cationic ion exchange resins were involved in the recovery process. The former ...

Abstract: Although conflict can be both functional and dysfunctional, unresolved conflict results in dissatisfaction and stress, thus reducing efficiency and productivity. However, personality affects the ability to handle conflict. ...

Abstract: A previously proposed nonlinear differential constitutive equation for creep-plasticity interaction under a uniaxial state of stress is specialized for the time independent case. The characteristics ...
