Inclined rectangular weir-flow modeling
WebfInclined Rectangular Weir- Flow Modeling: Shesha Prakash et al. Jain and Fischer (1982) have studied weirs with crest oblique to the flow axis in the channel. Multi fold skew weirs called Labyrinth weirs were developed and tested by Hay and Taylor (1970). They presented results in the form of curves WebThe flow and heat transfer characters in this situation is simulated by flow boiling of deionized water in an inclined rectangular channel under low flow rates. This paper aims to separate various parameters (such as orientation, mass flow rate and inlet quality, etc.) to investigate their individual effects on heat transfer coefficient (HTC ...
