Influence of Fuel-Oil Temperature on the Combustion in a Prechamber Compression-Ignition Engine

Description: Note presenting the influence of fuel-oil temperature on combustion as investigated by injecting the fuel into the prechamber of a single-cylinder, 4-stroke-cycle, water-cooled, compression-ignition engine operating at 1500 rpm and at a compression ratio of 13.5. The results showed that heating the fuel oil to 750 degrees Fahrenheit increased the injection period, changed the rate of injection, and eliminated the spray cone.

Cylinder Temperatures of Two Liquid-Cooled Aircraft Cylinders for Various Engine and Coolant Conditions

Description: Report presenting tests conducted with two liquid-cooled cylinders in order to isolate the effects of the various engine and coolant variables on cylinder temperatures and to obtain engine-cooling data required for a fundamental study of the heat-transfer processes in liquid-cooled engines. Cylinder temperatures were obtained for a large range of engine speeds, manifold pressures, carburetor-air temperatures, fuel-air ratios, spark advances, coolant-flow rates, average coolant temperatures, and… more

The Effect of Carburetor-Air Temperature on the Cooling Characteristics of a Typical Air-Cooled Engine Cylinder

Description: Report presenting an investigation that was conducted to determine the effect of carburetor dry-air temperature on the cooling characteristics of a typical full-scale air-cooled engine cylinder mounted on a single-cylinder crankcase.

Larval Development in Tropical Gar (Atractosteus tropicus) Is Dependent on the Embryonic Thermal Regime: Ecological Implications under a Climate Change Context

Description: Article presents research on how temperature affects fish populations. The study shows how changes in temperature may induce craniofacial and morphological alterations in fish during early stages and contribute to understanding the possible effects of global warming in early development of fish and its ecological implications.

Thermal Springs in the Boise River Basin, South-Central Idaho

Description: From purpose and scope: Purposes of this report are: (1) To define the areal distribution and occurrence of all thermal springs in the Boise River basin, (2) to evaluate their chemical and isotopic compositions, and (3) to quantify the amount of heat and water presently discharging from the springs.

Thermomagnetic Phenomena in Antimony at Liquid Helium Temperatures

Description: The purpose of this investigation was to study head-transport phenomena in a single crystal of antimony at liquid helium temperatures. In particular, the longitudinal and transverse components of the thermal resistivity tensor were measured as a function of magnetic field up to eighteen kilogauss.

Recording Rapidly Changing Cylinder-Wall Temperatures

Description: "The present report deals with the design and testing of a measuring plug suggested by H. Pfriem for recording quasi-stationary cylinder wall temperatures. The new device is a resistance thermometer, the temperature-susceptible part of which consists of a gold coating applied by evaporation under high vacuum and electrolytically strengthened. After overcoming initial difficulties, calibration of plugs up to and beyond 400 degrees C was possible" (p. 1).

Altitude cooling investigation of the R-2800-21 engine in the P-47g airplane 3: individual-cylinder temperature reduction by means of intake-pipe throttle and by coolant injection

Description: "Flight tests were conducted on a R-2800-21 engine in the P-47G airplane to determine the effect on the wall temperatures of cylinder 10 of throttling the charge in the intake pipe and of injecting a water-ethanol coolant into the intake pipe. Cylinder 10 was chosen for this investigation because it runs abnormally hot (head temperatures of the order of 45 F higher than those of the next hottest cylinder) at the medium and high-power conditions. Tests with interchanged cylinders showed that the… more

Laminar Free Convection on a Vertical Plate With Prescribed Nonuniform Wall Heat Flux or Prescribed Nonuniform Wall Temperature

Description: Note presenting an analysis made for laminar free convection on a vertical plate with nonuniform thermal conditions at the surface. Prescribed variations are considered for the wall heat flux and for the wall temperature. Graphs are presented from which the resulting wall-temperature variation may be obtained.

Investigations of Effects of Surface Temperature and Single Roughness Elements on Boundary-Layer Transition

Description: "The laminar boundary layer and the position of the transition point were investigated on a heated flat plate. It was found that the Reynolds number of transition decreased as the temperature of the plate is increased. It is shown from simple qualitative analytical considerations that the effect of variable viscosity in the boundary layer due to the temperature difference produces a velocity profile with an inflection point if the wall temperature is higher than the free-stream temperature" (p.… more

A Study of Heat and Mass Transfer to Uninsulated Liquid Oxygen Containers

Description: The wide use of liquid oxygen as an oxidant in rocket engines has resulted in an increased interest in low-temperature heat transfer. Storage tanks for this type of application, being uninsulated, contain a boiling-liquid low-temperature sink, which is susceptible to environmental heat inputs and subsequent liquid loss by vaporization. Such losses are difficult to predict due to the complex combination of ambient conditions which exist, and the lack of knowledge concerning their combined effect… more
