FEA Beyond Basics Thermal Analysis

2019-12-16
Finite Element Analysis (FEA) is a powerful and well recognized tool used in the analysis of heat transfer problems. However, FEA can only analyze solid bodies and, by necessity thermal analysis with FEA is limited to conductive heat transfer. The other two types of heat transfer: convection and radiation must by approximated by boundary conditions. Modeling all three mechanisms of heat transfer without arbitrary assumption requires a combined use of FEA and Computational Fluid Dynamics (CFD).

Automotive Heat Transfer

2019-05-06
Heat transfer affects the performance, emissions and durability of the engine as well as the design, packaging, material choice and fatigue life of vehicle components. This course covers the broad range of heat transfer considerations that arise during the design and development of the engine and the vehicle with a primary focus on computational models and experimental validation covering the flow of heat from its origin in the engine cylinders and its transfer via multiple paths through engine components.

R134a Refrigerant Charge Determination Test Method

2018-09-11
CURRENT
J3023_201809
The purpose of this document is to establish guidelines for determining the critical R134a refrigerant charge for off-road, self-propelled work machines as defined in SAE J1116 and Agricultural Tractors as defined in ANSI/ASAE S390. It will develop a minimum to maximum refrigerant charge range in which the HVAC system can maintain proper operation. Operating conditions and characteristics of the equipment will influence the optimum charge. Since these conditions and characteristics vary greatly from one application to another, careful consideration should be taken to determine the optimum R134a refrigerant charge for the HVAC system.

COOLING FLOW MEASUREMENT TECHNIQUES

1992-06-01
HISTORICAL
J2082_199206
This SAE Information Report has been prepared by the Standards Committee on Cooling Flow Measurement (CFM) at the request of the SAE Road Vehicle Aerodynamics Forum Committee (RVAC). The committee was formed in January 1985 for the purpose of investigating what measuring techniques are used by automotive product manufacturers to determine air cooling air flow rates and, if possible, to synthesize these into a recommended practice report. Although a great deal is already known about engine cooling, recent concern with fuel conservation has resulted in generally smaller air intakes whose shape and location are dictated primarily by low vehicle drag/high forward speed requirements. The new vehicle intake configurations make it more difficult to achieve adequate cooling under all conditions. They cause cooling flow velocity profiles to become distorted and underhood temperatures to be excessively high.

Cooling Flow Measurement Techniques

CURRENT
J2082_201809
This SAE Information Report has been prepared at the request of the SAE Road Vehicle Aerodynamics Forum Committee (RVAC), incorporating material from earlier revisions of the document first prepared by the Standards Committee on Cooling Flow Measurement (CFM). Although a great deal is already known about engine cooling, recent concern with fuel conservation has resulted in generally smaller air intakes whose shape and location are dictated primarily by low vehicle drag/high forward speed requirements. The new vehicle intake configurations make it more difficult to achieve adequate cooling under all conditions. They cause cooling flow velocity profiles to become distorted and underhood temperatures to be excessively high. Such problems make it necessary to achieve much better accuracy in measuring cooling flows.

Measurement of Passenger Compartment Refrigerant Concentrations Under System Refrigerant Leakage Conditions

2011-02-04
CURRENT
J2772_201102
This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate concentration inside the passenger compartment. In the early phases of vehicle evaluation, usage of the analytical approach may be sufficient without performing physical tests. The physical test procedure involves releasing refrigerant from an external source to a location adjacent to the evaporator core (inside the HVAC-Module). An apparatus is used to provide a repeatable, calibrated leak rate. If the system has multiple evaporators, leakage could be simulated at any of the evaporator locations. This standard gives detail information on the techniques for measuring R-744 [CO2] and R-1234yf [HFO-1234yf], but the general techniques described here can be used for other refrigerants as well.

SAE MANUAL ON BLAST CLEANING

1968-06-01
CURRENT
J792A_196806
Blast cleaning may be defined as a secondary manufacturing process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. As indicated in the definition, blast cleaning may be employed for a variety of purposes. Ordinarily, it is considered as a method for removing sand from castings, burrs or scale from forgings, mill products, or heat treated parts; to promote machinability, and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces an excellent surface for industrial coatings. All these objectives are often accomplished in the one operation.
