Heat Transfer and Boiling Studies
Research Guide

Taitel and Dukler (1976) presented models based on physical concepts for predicting transitions in horizontal and near-horizontal gas-liquid flow without relying on empirical flow regime data. These models use a generalized flow regime map incorporating fluid properties and pipe geometry. The approach is fully predictive for stratified, intermittent, and annular regimes.

J. C. Chen (1966) established a correlation for boiling heat transfer to saturated fluids in convective flow, published in Industrial & Engineering Chemistry Process Design and Development. It predicts heat transfer coefficients based on flow conditions and fluid properties. This relation applies to nucleate boiling regimes in tubes and channels.

Taitel, Barnea, and Dukler (1980) developed models for steady upward gas-liquid flow in vertical tubes, based on physical mechanisms for transitions like bubbly to slug and slug to churn. The models account for fluid properties and pipe size, avoiding empirical limitations. They predict patterns including annular and dispersed bubble flows.

Studies cover heat transfer characteristics in microchannels, pulsating heat pipes, and heat exchangers as noted in the field description. Convective boiling involves two-phase flow regimes analyzed in papers like Taitel and Dukler (1976). Condensation processes link to pool boiling and nucleate boiling fundamentals.

Wang and Mujumdar (2006) reviewed heat transfer characteristics of nanofluids, showing enhanced boiling performance due to nanoparticle suspensions. Nanofluids improve critical heat flux and reduce wall superheat in pool and flow boiling. Applications target high-heat-flux scenarios in electronics cooling.
