A study on the internal convection in small turbochargers. Proposal of heat transfer convective coefficients

Abstract: Nowadays turbochargers play an important role in improving internal combustion engines (ICE) performance. Usually, engine manufacturers use computer codes to predict the behaviour of both engine and turbocharger, the later by means of measured look-up maps. Using look-up maps different problems arise, being one of the most important the difference in heat transfer between the current operating condition and the conditions at which maps were measured. These effects are very important at low to medium turbocharg… Show more

“…For example, one of the inconveniences of piezo-electric pressure sensors, such as the ones commonly used in research and validation applications [19], is the measurement of the in-cylinder pressure derivative (dp), and not the pressure value. Normally, an additional piezo-resistive sensor is used at the intake in order to set the pressure level at the intake valve closing (IVC) [20].…”
