- •
Heat transfer characteristics of three types of EGR coolers (Semi, Full spiral and Full-smooth) were investigated.
- •
Pressure drop in the F-Spiral EGR cooler is more than other EGR coolers.
- •
The F-spiral and S-spiral EGR cooler is suggested to be utilized in diesel engine.
- •
Heat transfer efficiency of the S-spiral is 0.17 higher than that of the F-smooth EGR cooler.
- •
The heat transfer efficiency of the S-spiral and F-spiral EGR cooler are same.
