In the further development of nuclear fusion energy, managing high heat flux on a divertor target remains significant issue. To address this, innovative cooling channels capable efficiently loads is essential. Among various techniques, hypervapotron (HV) method stands out for its exceptional transfer capabilities. This study undertakes an in-depth analysis novel HV channel, evaluating performance via electron beam testing system. The focus was subcooled flow boiling, observing that channel displayed varied patterns with increasing flux. Additionally, comparative investigation conducted to assess efficiency this against traditional ITER-like and smooth channel. incorporated system parameters, such as mass rate pressure, understand their effects transfer. effectively predict efforts have been made evaluate existing develop new correlations Furthermore, Artificial Neural Networks (ANNs) also utilized crucial approach in predictive endeavor. outcomes hold implications understanding optimizing design reactors.
