研究室紹介
Professor Koo Junemo's research lab specializes in microscale fluid dynamics, advanced materials for energy and electronics, and predictive modeling for sustainability. The lab investigates microchannel flow behaviors, focusing on deviations from macro-scale theories due to wall slip, viscosity changes, and surface effects, while also developing high-performance materials such as PZT capacitors for next-generation memory devices. Another key focus is on enhancing thermal performance using nanofluids with carbon nanotubes and nanofibers, grounded in physical principles like excluded volume theory. Additionally, the lab applies meta-modeling techniques to optimize building energy consumption and predict food quality, particularly egg freshness, using statistical sampling methods like Latin Hypercube Sampling.

15Experimental observations of liquid microchannel flows are reviewed and results of computer experiments concerning channel entrance, wall slip, non-Newtonian fluid, surface roughness, viscous dissipation and turbulence effects on the friction factor are discussed. The experimental findings are classified into three groups. Group I emphasizes 'flow instabilities' and group II points out 'viscosity changes' as the causes of deviations from the conventional flow theory for macrochannels. Group III
Interest in research analyzing and predicting energy loads and consumption in the early stages of building design using meta-models has constantly increased in recent years. Generally, it requires many simulated or measured results to build meta-models, which significantly affects their accuracy. In this study, Latin Hypercube Sampling (LHS) is proposed as an alternative to Fractional Factor Design (FFD), since it can improve the accuracy while including the nonlinear effect of design parameters

The capacitor has 0.25mum diameter and 0.4mum depth. Three layers, Ir(20nm)/PZT(60nm)/Ir(20nm
The compactness and high surface-to-volume ratios of microscale liquid flow devices make them attractive alternatives to conventional flow systems for heat transfer augumentation, chemical reactor or combustor miniaturization, aerospace technology implementations, as well as biomedical applications, such as drug delivery, DNA sequencing, and bio-MEMS, to name a few. While experimental evidence indicates that fluid flow in microchannels, especially in terms of wall friction and heat transfer perf
The overall aim of this research was to develop egg freshness prediction models in terms of selected quality indices. Six experiments (4 constant temperatures and 2 variable temperatures) were carried out on hen eggs for a total period of 10, 21, 26, 13, and 105 d at storage temperatures of 30, 20, 20 to 10, 30 to 10, and 5 and 10°C, to observe trends in the relative weight loss (RWL), Haugh unit (HU), yolk index (YI), albumin index (AI), yolk pH, and albumin pH. The results showed that there wa
