Parametric studies on packed bed storage unit filled with PCM encapsulated spherical containers for low temperature solar air heating applications

Review of the application of phase change material for heating and domestic hot water systems

“…Karthikeyan et al [74] used spherical capsules filled with paraffin in packed bed storage for low temperature air heating applications. They developed a mathematical model, which was validated using experimental data from similar configuration as obtained from previous literature.…”

Potential of adaptive neuro-fuzzy system for prediction of daily global solar radiation by day of the year

“…Solar energy has been recognized in recent years as a proper alternative energy source owing to its unique characteristics which is free, environmental friendly and broadly accessible in most locations across the globe [1,2]. In this regard, countries are performing tremendous efforts to assign a high priority to solar energy harnessing.…”

Parametric investigation on thermo-hydraulic performance of wire screen matrix packed solar air heater

“…For the same range of flow rate, efficiency of double pass is 34-45% higher than single pass and the maximum efficiency attained in single and double pass is 45.93% and 83.65% respectively for the flow rate of 0.038 kg/s. Karthikeyan et al [12] performed parametric studies on the performance of a packed bed storage unit filled with phase change material (PCM) encapsulated spherical containers, suitable for low temperature solar air heating applications. A parametric analysis was carried out using the validated enthalpy based numerical model that considers the thermal gradient inside the PCM container.…”
