Abstract

The melting of a phase change material (PCM) in a cavity with a gradient of hot wall inclination was simulated numerically using five models, namely, Model-A, Model-B, Model-C, Model-D, and Model-E with gradients of −2, −4, ∞, 4, and 2, respectively. The PCM was paraffin wax, which was melted using an enthalpy porosity technique with a pressure-based method. Model-A was found to be the best model. For the completion of the melting process, the models were assigned with the liquid fraction of 1. Model-A required the shortest time, followed by Model-B, Model-C, Model-E, and Model-D, respectively. Compared with Model-C, Model-A was 9.4% faster, Model-B was 3.8% faster, Model-D was 2.3% slower, and Model-E was 3.2% slower.

Bahasa Abstract

Peleburan material berubah fasa dalam sebuah rongga dengan gradien kemiringan dinding panas telah disimulasikan secara numerik menggunakan lima model, yaitu Model-A, Model-B, Model-C, Model-D, dan Model-E dengan gradien kemiringan sebesar 2, 4, ∞, 4, dan 2. Material berubah fasa yang digunakan adalah parafin, proses peleburan menggunakan teknik enthalpy porosity dengan metode pressure-based. Model-A ditemukan sebagai model terbaik. Untuk penyelesaian proses peleburan, ditandai dengan fraksi cair bernilai 1. Model-A membutuhkan waktu tersingkat, diikuti oleh Model-B, Model-C, Model-E, dan Model-D. Dibandingkan dengan Model-C, Model-A 9,4% lebih cepat, Model-B 3,8% lebih cepat, Model-D 2,3% lebih lambat, dan Model-E 3,2% lebih lambat.
