Machine tools are used to cut and shape metals and nonmetallic materials based on the specifications of a product. The tools, which aid in the manufacturing of critical components, include metal-cutting machine tools, metal-forming machine tools, and machine tools accessories.

Pumps circulate coolants or lubricants throughout machines and other equipment and thus increase the operational performance of industrial plants. A PD pump moves a fluid by trapping a fixed volume of the fluid and then forcing it into the discharge pipe. PD pumps are widely used in the mining, oil and gas production, oil refining, chemical, power generation, food and beverage, machinery, aerospace, shipbuilding, automotive, pharmaceutical, pulp and paper, marine, water and sewerage, agriculture, and construction industries.

In the oil and gas industry, pressure vessels — called separators — are used to segregate well streams into liquid and gaseous components. Separators are used in a range of applications, including on-site primary separation and refinery process separation. The main types of separators are horizontal, vertical, and spherical; these can be further divided into two groups based on the fluids to be separated, namely, oil/gas/water three-phase separators and liquid/gas two-phase separators. Based on application, separators can also be classified as primary-phase separators, test separators, low-pressure separators, high-pressure separators, degassers, or deliquizers. Separators are usually designed in three stages to meet the specific requirements of a project.

Pumps are mechanical devices that transfer fluid from one place to another. These devices use electricity, wind power, and engines as energy sources. They are used in the agriculture, water and wastewater, power generation, mining, chemical processing, hydrocarbon processing, food and beverage, oil and gas, pulp and paper, and aerospace industries.

This article presents a thermo-mechanical approach to investigate heat transfer between solid and fluid phases in a model gasifier. A two-temperature equation approach is applied in addition to a macroscopic model for laminar flow through a porous moving bed. Transport equations are discretized using the control-volume method and the system of algebraic equations is relaxed via the SIMPLE algorithm. The effects on inter-phase heat transfer due to variation of medium permeability, thermal conductivity and thermal capacity are analyzed. Results indicate that for smaller medium permeabilities, as well as for higher solid-to-fluid thermal capacity and thermal conductivity ratios, enhancement of heat transfer between phases is observed.

This project centered on a close interaction between the TCON Division of Fire line, Inc. and various individuals affiliated with the College of Science, Technology, Engineering, and Mathematics (STEM) at Youngstown State University (YSU). Fireline, a local company within 10 minutes walking distance from the YSU campus core, has developed a unique process that utilizes displacement reactions to transform ceramic preforms into ceramic-metallic co-continuous interpenetrating phase composites with enhanced properties while retaining the original shape and dimensions of the preform. Through initial development efforts, it was discovered that TCON(TradeName) composite materials have extraordinary macro-, micro-, and nanoscale features that lead to their exceptional properties ideal for applications that require cost effective, lightweight materials. The unique properties of TCON composites in general are derived from the fine interlocking of ceramic and metallic phases throughout the composite microstructure. The ceramic phase provides high stiffness, low density and high strength to the composite, while the continuous network of reinforced metal gives high thermal & electrical conductivity, and high fracture toughness to the material. Such properties make these materials excellent candidates for replacing traditional materials in a number of applications, such as high wear/corrosion resistant refractory shapes for molten metal transport and/or containment in industrial processes (the major area in which Fireline currently commercializes some of its TCON products), or for new applications, including light weight, high strength components for vehicle braking systems.

Use of customer owned controllable load, heat pump water heater (HPWH), has been considered for voltage control in distribution system with large penetration of photovoltaic systems. Primary control priority of the proposed voltage control methods is to ensure sufficient amount of hot water in the HPWH tank so that none of participating consumer are affected with hot water shortage. In order to prevent hot water shortage problem, time-varying trigger level to operate the HPWH at right time has been proposed by considering amount of hot water in the tank and hot water consumption. The proposed method triggers the HPWH operation with rated power consumption when amount of hot water in the tank reaches below the proposed trigger level. Outcome of hot water demand patterns.
