Measurements of heat collection rate and heat loss coefficient are crucial for the evaluation of in service water-in-glass evacuated tube solar water heaters. However, conventional measurement requires expensive detection devices and undergoes a series of complicated procedures. To simplify the measurement and reduce the cost, software based on artificial neural networks for measuring heat coll...
Measuring condensation heat transfer and its associated coefficient is not trivial. Rigorous measurements require careful experimental design tradeoff studies to properly select sensor type, sample geometry size, coolant fluid flow rate, operating conditions, working purity, purge methodology, measurement protocol. Conventional tube-based quantify the change in enthalpy of a single-phase via in...
In this investigation, nucleate boiling heat transfer coefficients were experimentally measured during pool boiling of mixtures, consisting of water/monoethanolamine and water/diethanolamine on a horizontal heating rod, under atmospheric pressure. The experiment was carried out below 205 kW.m-2 heat flux, over a wide range of concentrations. These experiments include, measurement of pool boilin...
