ENGINE-COOLING SYSTEMS AND RADIATOR CHARACTERISTICS 1 240013

In the first part of the paper, a general quantitative comparison of air, water and oil-cooled cylinders is given as it relates to the subject of heat-transfer and temperature drop. Unfortunately, the discussion does not include experimental data, but the assumptions are stated clearly and a large range of values is covered in Table 2 so that any desired values can be chosen. A thorough and comprehensive discussion of the steam or the radio-condenser type of cooling is given under the headings of Steam Cooling Systems, Characteristics of Steam Cooling Systems, Cooling Capacity of Radiators Used To Condense Steam and Present State of Development.
In the second part, an attempt is made to give a thorough but brief discussion of the performance or of the operating characteristics of radiators from the point of view of the car, truck or tractor designer. The cooling of aircraft engines is not considered. A great amount of original material is contained in this second part which should prove not only of direct value and use, but also of indirect value by interesting others in the solution of cooling problems. A summary is given at the end from which some of the salient points can be obtained without making a detailed study of the paper.
