The paper describes a study that forms part of a measurement assurance program (MAP) in place at Ford Motor Company. The purpose of a MAP is to assure on an ongoing basis that the total uncertainty associated with a measurement process meets the requirements of the customer. The gage repeatability and reproducibility study and statistical control chart are two traditional parts of the Ford MAP....

We present simulations of Mach 12, 3D, hypersonic turbulent flows of air around blunt bodies with applied magnetic fields of various strengths. We use the Baldwin-Lomax turbulence model. The air is heated by a shock that can change its thermodynamic properties. We treat the air as a real gas in thermodynamic equilibrium. Due to the high temperature the thermodynamic properties of the air are af...

Abstract Energy crisis is a major challenge in the current world. Latent heat thermal energy storage (LHTES) systems are known as equipment with promising performance by which thermal energy can be recovered. In the present study a comprehensive theoretical and experimental investigation is performed on a LHTES system containing PEG1000 as phase change material (PCM). Discussed topics can be ca...

For centuries, dome roofs were used in traditional houses in hot regions such as the Middle East and Mediterranean basin due to its thermal advantages, structural benefits and availability of construction materials. This article presents the computational modelling of the windand buoyancy-induced ventilation in a geodesic dome building in a hot climate. The airflow and temperature distributions...

Twenty-three children (12 boys and 11 girls) and 13 female students served as the subjects in summer. The children were from six to eight years old. The subjects were seated in a hot room of 300C and their !egs were immersed in bath water of 42eC for 30 minutes. Total sweat rate, local sweat rate on the back, rectal temperature, skin temperatures at eight sites, heart rate and blood pressure we...

TAYLOR, c. R. Metabolism, respiratory changes, and water balance of ~12 antelope, the eland. Am. J, Physiol. 217(l) : 3 17-320. 1969. The eland is a large East African antelope which can survive prolonged droughts in hot semideserts without drinking. This ability is partly due to a low respiratory water loss relative to the oxygen consumption at night. Each night the eland has a low body temper...

We present work on 3D hypersonic laminar flows of air around blunt bodies with applied magnetic fields of various strengths. The air is heated by a shock that can change its thermodynamic properties. We treat the air both as a calorically perfect gas (chemically frozen) and as a real gas in thermodynamic equilibrium. Due to the high temperature the thermodynamic properties of the air are affect...

This paper presents a comprehensive refinement of system modeling and optimization study of air-cooled direct expansion (DX) refrigeration systems for commercial buildings to address the energy saving problem. An actual DX rooftop package of a commercial building in the hot and dry climate condition is used for experimentation and data collection. Both inputs and outputs are known and measured ...

ABSTRACT- Drying has been used for the preservation of fruits since ancient times. Dried apricot reduces the damages, weight and volume losses, packaging space, storage and handling costs. In this paper, the effects of hot air dryer on an Iranian apricot cultivar ”Noori” have been investigated. The experiment was conducted at three temperatures (30, 40 and 50oC), three fruit thicknesses (5, 10 ...
