Steady state and stability characteristics of natural circulation loops operating with carbon dioxide at supercritical pressures for open and closed loop boundary conditions
TL;DR: In this article, a computer code NOLSTA has been developed to carry out steady state and stability analysis of open and closed loop natural circulation at supercritical conditions, which predicts very large unstable zone for SPNCL, hence pipe wall thermal capacitance models were incorporated to simulate the experimental results.
Journal ArticleDOI
Recent development on biodegradable nanolubricant: A review
Sathuramalingam Pillay Darminesh,Nor Azwadi Che Sidik,Nor Azwadi Che Sidik,Gholamhassan Najafi,Rizalman Mamat,Tan Lit Ken,Yutaka Asako +6 more
TL;DR: In this paper, the authors reviewed the current progress and recently published data related to biodegradable lubricant, nanoparticles and its improvement on the biodesgradable oil properties.
Journal ArticleDOI
Heat Transfer Characteristics of Gaseous Flows in a Microchannel and a Microtube with Constant Wall Temperature
Chungpyo Hong,Yutaka Asako +1 more
TL;DR: In this paper, the heat transfer characteristics of gaseous flows in a microchannel and a microtube with constant wall temperature, whose temperature is lower than the inlet temperature (cooled case), were investigated.
Journal ArticleDOI
Control of immersion nozzle outlet flow pattern through the use of swirling flow in continuous casting
TL;DR: In this paper, a water model is used to investigate the effect of imparting a swirl flow in the entrance region of a nozzle, which is aimed at making the injection velocity more uniform and reducing the disturbance of the free surface.
