Numerical investigation of the heat transfer and friction factor characteristics of a circular fitted with V-cut twisted tape (VCT) insert with twist ratio (y = 2.93) and different cut depths (w = 0.5, 1, and 1.5 cm) were studied for laminar flow using CFD package (FLUENT-6.3.26). The data obtained from plain tube were verified with the literature correlation to ensure the validation of simulat...

Many components of the storage ring and front ends in the third generation of light sources are subjected to high heat loads from intense x-rays. Temperature rises and thermal stresses in these components must be kept within acceptable limits of critical heat flux and low-cycle fatigue failure. One of the design solutions is to improve heat transfer to the cooling water either by increasing wat...

• Microchannel heat sinks are modelled by conjugate transfer and laminar flow CFD. Four performance enhancement tape inserts tested individually combined. Tape axial twist improves the Nusselt number gains to hydraulic loss trade-off. With best heated base is 16 ℃ cooler at 100 W/cm 2 flux input. Sealing in barrel prevents tip leakage raises conduction. The continuous power increase miniaturiza...
