Nucleate and Film Boiling of Engine Coolants Flowing in a Uniformly Heated Duct of Small Cross Section

Vehicular Engine Design

“…The first paper listed is a computational study of the effect of including boiling in thermal analysis of engine components (see Bo 2004;Finlay and Parks 1985;Norris et al 1989Norris et al , 1993Norris et al , 1994Campbell et al 1999;Finlay et al 1987).

Heat Transfer Regimes in the Coolant Passages of a Diesel Engine Cylinder Head

“…This represents a "worst-case" condition. If the system were pressurized and the water replaced with a water/ethylene glycol mixture, a transition to boiling would occur at higher wall temperatures [1].…”

“…Heat transfer in several regimes may occur in the coolant passages of a liquid-cooled cylinder head [1]. At low wall temperatures, heat transfer to the subcooled coolant is by pure forced convection, and the heat flux increases linearly at a moderate rate with increasing wall temperature.…”

Pressure drop, heat transfer, critical heat flux, and flow stability of two-phase flow boiling of water and ethylene glycol/water mixtures - final report for project "Efficent cooling in engines with nucleate boiling."

“…In addition, precision cooling using the 50/50 EG/W liquid mixture is limited by the coolant liquid properties and the cooling system geometry. Because of its order-of-magnitude higher heat transfer rates, there is interest in using controllable two-phase nucleate boiling instead of conventional single-phase forced convection in vehicular cooling systems under certain conditions or in certain areas of the engine to remove ever increasing heat loads and to eliminate potential hot spots in engines [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”
