Heat transfer during spray water cooling using steady experiments
Spray water cooling is widely used in many industrial processes to control heat removal from a hot material surface. In order to control heat transfer rates and obtain desired surface temperature distributions, a deeper understanding of fundamental spray cooling dynamics and more accurate …

Reliability improvement project decision making : water cooling system redesign
Deciding on which reliability & performance improvement projects to launch or to reject has historically been an extremely challenging responsibility of Teradyne management. Incorrect decisions can lead to major customer dissatisfaction, which may subsequently lead to loss of market share. Teradyne …

Development and experimental analysis of a novel hybrid cooling concept for electric vehicle batteries
In this thesis, a novel hybrid cooling concept for electric batteries is developed and studied at both the cell-level and pack-level experiments. The concept is based on a simple air-cooling duct that utilizes enhanced water vaporization by convection to achieve an effective cooling. A series of …

Image segmentation based on water flow analogy
… presents a new method, based on the paradigm of water flow. The mechanism embodies the fluidity of water and thus can deal with complicated objects. A snake-like force functional is utilized, including edge-based and region-based forces, guiding extraction to select the target feature. Water …

An Investigation of Heat Transfer to the Implant-Bone Interface and Marginal Gingiva During Preparation of Implant Abutments in the Mouth: in vitro study
… during 30 seconds. The specimen was placed under water of 37°C and the temperature was maintained throughout the procedure. The data was gathered using the K type thermocouple as the temperature measuring sensor, the LabView(National Instument, Texas, US) as the software in the monitoring system, …

Effect of liquid flow patterns on distillation trays
… experimental work on sieve trays in an air-water simulator, 2.44 m in diameter. The liquid flow pattern, for flowrates similar to those used in commercial scale distillation, was observed experimentally by water cooling experiments, in which the temperature of the water is measured at over …

Flow patterns on distillation trays
… on a sieve tray were carried out using an air-water simulator of 2.44 m in diameter. The flow patterns were investigated by a number of methods, direct observation using directional flow pointers; by water-cooling to simulate mass transfer; and by measurement of the height of clear liquid …

A Dynamic Model Of The Human/cooling System/clothing/environment System
… also lead to substantial heat stress. Personal cooling is widely used to alleviate heat stress, especially for those situations where ambient environmental cooling is not economically viable or feasible. It is important to predict the physiological responses of a person wearing PPE with personal …

Flow patterns and performance of distillation trays
… a new experiment which simulates distillation by water cooling. and provides a means of testing commercial size trays in the laboratory. Hot water is fed on to the tray and cooled by air forced through the perforations. The analogy between heat and mass transfer shows that the water temperature at …

Design and fabrication of an internal condensation loop for effectiveness and robustness testing of nanostructured superhydrophobic steam condenser
… Industrial condensers feature once-through water cooling, and the substantial amount of water they consume coupled with the increasing scarcity of freshwater supplies provides further motivation to focus on the condensation process. Condensation in these systems occurs predominantly via the …

Investigation of the cooling characteristics of rotating liquids
In this paper, an analysis of the internal water-cooling of a gas turbine was carried out. The density differences due to heating of the water in the blade and drum, combined with the very large force field associated with the centrifugal force caused by the rotation of water, sets up strong …
