In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
Current internal combustion engine technology centres around the need for high energy density products to reduce the size and mass of engines, allowing for improved vehicle performance. This and the addition of emission reduction ancillaries to meet engine emissions legislation has led to much greater heat rejection into engine cooling systems since these typically require cooling. It is known that the coolant liquid flow circulates with entrained gas which reduces the performance of the coolant system by de-rating the centrifugal pump and altering the fluid heat transfer and turbulence properties. The source of this gas cannot be remedied hence a device or method is required in the coolant system to remove the entrained gas from the flow. [Continues.]
