New effective thermal conductivity model for the analysis of whole thermal storage tank

•A new effective thermal conductivity model was proposed.•A whole thermal storage tank with 9 × 9 × 20 spherical capsules was modeled.•Individual melting behavior was captured for each capsule in relation to position.•Many drawbacks in earlier effective thermal conductivity models were overcome. In...
