experimental investigation of surface roughness effect on flow boiling in internal combustion engine water jacket

the subjects of heat transfer and cooling system are very important topics in the internal combustion engines (ice). in modern cooling systems, low weight, small size and high compactness are the critical designing criteria that requires heat transfer enhancement. boiling phenomenon which is occurred in the water jacket of the ice is one of the methods to increase heat transfer in the coolant s...

Simulation of Subcooled Flow Boiling Occurring in Internal Combustion Engine Water Jacket by Numerical Modeling in a Channel with Hot Spot

Boiling heat transfer always has been proposed as a solution for enhancing heat transfer between the fluid and solid surfaces. Subcooled flow boiling is one of the mechanisms that occur in Internal Combustion Engine water jacket in which high amounts of heat is transferred. In this research, it has been tried to simulate subcooled flow boiling in a geometry similar to coolant channel inside the...

Two Phase Flow Simulation for Subcooled Nucleat Boiling Heat Transfer Calculation in Water Jacket of Diesel Engine

Basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. Coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. An efficient approach to studying cooling system for diesel engine is a 3D computational fluid dynami...

Experimental Investigation of Thermal Balance and Valve Cover Heat Transfer in a Small Internal Combustion Engine

Heat transfer in internal combustion engines is one of the most significant topics. Heat transfer may take place through thermal conduction and thermal convection in spark ignition engines. In this study, valve cover heat transfer and thermal balance of an air-cooled engine are investigated experimentally.

Simulation of Boiling Heat Transfer within Water Jacket of 4-cylinder Gasoline Engine (TECHNICAL NOTE)

Shrinking the engine has been a great interest for many years. Providing more amount of heat transfer may supply possibilities for size reduction in engine parts specifically the engine water jacket that is of concentration for the present study. Boiling phenomenon, by providing more amounts of heat transfer in comparison with single-phase, provides conditions for size reduction. In this paper ...
