A compact aluminium intercooler for supercharge air for use in cars and trucks was numerically studied moving from an overall approach to a deep insight in finnings. The influence of different input values of cooling and supercharge air flowrates was observed, investigating microscopic effects on the flow field, on heat transfer local convective coefficients and macroscopic effects on performance variations in terms of heat transfer and pressure losses. Triangular wavy finnings, trapezoidal offset strip finnings (squared and rounded, single or coupled) and inside finned tubes efficiencies were calculated with reference to the different input conditions, useful for possible correlation equations among adimensional parameters for future design and sizing activities.

Abstract
A compact aluminium intercooler for supercharge air for use in cars and trucks was numerically studied moving from an overall approach to a deep insight in finnings. The influence of different input values of cooling and supercharge air flowrates was observed, investigating microscopic effects on the flow field, on heat transfer local convective coefficients and macroscopic effects on performance variations in terms of heat transfer and pressure losses. Triangular wavy finnings, trapezoidal offset strip finnings (squared and rounded, single or coupled) and inside finned tubes efficiencies were calculated with reference to the different input conditions, useful for possible correlation equations among adimensional parameters for future design and sizing activities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
