One of the functions of a cowl area in a vehicle is the separation of water and air flow. A well working separation of water droplets in the airflow is required under all circumstance, to avoid the blower or air filter to become wet. Airflow calculations help improving the design of the cowl to achieve an effective water droplet separation and simultaneously low pressure losses. The proposed design has been tested under sever conditions. Test results were compared to theoretical results and revised design requirements will be proposed.

This SAE Standard provides manufacturers/marketers, testing facilities and providers of technician training with a procedure for certifying compliance with the applicable standard. Manufacturers/marketers or sellers who advertise their products as Certified to an SAE J standard shall follow this procedure. Certification of a product is voluntary; however, this certification process is mandatory for those advertising meeting SAE Standard(s) requirements. Only certifying to this standard allows those claiming compliance to advertise that their product (unit), component, or service technician training meets all requirements of the applicable SAE standard.

Abstract The ever increasing popularity of electric vehicles and higher requirement on safety and comfort has led heat pump air conditioning system indispensable in electric vehicle. Many studies have shown that the addition of nano particles contributes to great improvement on thermal conductivity than that of conventional refrigerants. Therefore, the application of the magnetic nanorefrigerant in heat pump air conditioning system has massive potential to heighten the heat transfer efficiency. This paper aims at studying the magnetic nanorefrigerant comprised of the magnetic nano powder Fe3O4 and refrigerant R134a. According to the relevant theoretical analyses and empirical formula, the heat transfer coefficient, density, viscosity, and other physical parameters are calculated approximately.

Abstract For thermal cabin control of commercial aircraft, the cabin is usually divided into a small number of temperature zones. Each zone features its own air supply pipe. The necessary installation space for ducting increases significantly with the number of zones. This requires the number of temperature zones to be low. Factors such as seating layout, galley placement and passenger density result in deviations in heat flux throughout the cabin. These deviations cannot be compensated by the control system, if they occur within the same temperature zone. This work presents a novel temperature regulation concept based on local mixing. In this concept, two main ducts span the complete cabin length, and provide moderately warm and cold air. At each temperature zone, cabin supply air is locally mixed using butterfly valves.

This SAE Aerospace Information Report (AIR) outlines concepts for the design and use of fault isolation equipment that have general application. The specific focus is on fault isolation of environmental control systems (ECS) in commercial transports. Presented are general fault isolation purposes, design principles, and demonstration of compliance criteria. These are followed by three design examples to aid in understanding the design principles. Future trends in built-in-test-equipment (BITE) design are discussed, some of which represent concepts already being implemented on new equipment.

This SAE Information Report is a source of information concerning the basic properties of engine coolants which are satisfactory for use in internal combustion engines. Engine coolant concentrate (antifreeze) must provide adequate corrosion protection, lower the freezing point, and raise the boiling point of the engine coolant. For additional information on engine coolants see ASTM D 3306 and ASTM D 4985.

The values presented describe desirable basic properties. The results from laboratory tests are not conclusive, and it should be recognized that the final selection of satisfactory coolants can be proven only after a series of performance tests in vehicles.

The document describes in general the necessary maintenance procedures for all engine coolants to insure proper performance as well as special requirements for coolants for heavy-duty engines.

This document does not cover maintenance of engine cooling system component parts.
