RISFlow and Heat Transfer Characteristics in the Entry and Stabilized Flow Regions of a Circular Channel Rotating About a Parallel Axis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cooling of heavy-duty electrical machines such as generators and motors is crucial for the smooth operations without thermal runaway. A commonly employed technique for the cooling of rotors in these machines is to place ...
Numerical Investigation and Multi-Objective Optimization of Attached and Detached Inclined Ribs in an Annular Channel for Enhanced Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study presents a detailed numerical investigation into local heat transfer enhancement in a double-pipe heat exchanger (DPHE) using attached and detached ribs as turbulence promoters. Ribs are a simple device ...
Thermal Characteristics of a Three-Dimensional Coil Type Pulsating Heat Pipe at Different Heating Modes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heat transfer performance of a pulsating heat pipe (PHP) configured as a three-dimensional (3D) structure is reported in the present study. The PHP structure resembles an elongated coil and termed “coil type PHP.” Five ...
