Samir Kadunic stellt ein wirkungsvolles Modell zur Brennverlaufsvoraussage im Ottomotor vor und veranschaulicht die Vorteile, die sich durch das Einbinden der PKW-Klimaanlage in die Ladeluftkühlung ergeben. Eine kontrollierbare niedrige Ladelufttemperatur erlaubt danach eine von der Außenlufttemperatur unabhängige Auslegung der ottomotorischen Verbrennung. Diese niedrige Ladelufttemperatur hat ein erhebliches Potenzial, den Wirkungsgrad und die Leistungsdichte des aufgeladenen Ottomotors noch weiter zu steigern. Dafür ist es notwendig, die erreichbare Ladelufttemperatur möglichst weitgehend von den Umgebungsbedingungen zu entkoppeln. Die PKW-Klimaanlage steht für die Ladeluftkühlung als bisher ungenutztes Kältereservoir zu Verfügung. Mit Messungen auch am Motorprüfstand konnte der Autor zeigen, dass trotz eingeschalteter Klimaanlage der Kraftstoffverbrauch verringert und die Leistung gesteigert werden kann.

This monograph introduces a numerical computational technique for thermal functionality modeling of cross-flow warmth exchangers, with functions in chemical, refrigeration and car industries. this technique permits acquiring effectiveness-number of move devices (e-NTU) information and has been used for simulating a number of ordinary and complicated circulation preparations configurations of cross-flow warmth exchangers. Simulated effects were confirmed via comparisons with effects from on hand targeted and approximate analytical recommendations. Very exact effects were received over vast levels of NTU and C* values in all circumstances. The proposed approach constitutes an invaluable examine device for either theoretical and experimental reports of cross-flow warmth exchangers.

The following are the original good points of the book:

- The monograph contains the computational code named HETE (Heat Exchanger Thermal Effectiveness) in bankruptcy five. A model of this code is obtainable for downloading.

- The computational process may be used for decreasing experimental information utilizing the effectiveness - NTU (e-NTU) approach in learn and business laboratories.

- Even after a couple of century in warmth exchanger examine, the quest for brand new circulate preparations with better effectiveness nonetheless is an unsolved challenge. the current technique can be a great tool in pursuing that goal.
