A fundamental study of flow characteristics and heat transfer in multiple burner oilfired marine boilers.

摘要

This study has shown that the main characteristics of axial velocityuddecay and recirculation in multiple enclosed jets can be related to thoseudof single enclosed jets. This is achieved by considering each jet to beudbounded by an imaginary duct whose dimensions can be related to the nozzleudspacing parameters. If the nozzles are close together compared with theudsurrounding chamber, the above treatment is only valid near- to the nozzles.udFurther downstream the jets coalesce and their behaviour can be related toudthat of a single jet by an equivalent nozzle radius.
