Abstract

This paper presents the computational of two-way fluid structure interaction technique by using Mesh based Parallel Code Coupling Interface for the visualization of wiresweep in the electronics packaging. Polymer rheology with Castro-Macosko model have been used in the fluid flow model and Volume of Fluid technique was applied to melt front tracking of the fluid. The numerical analysis used User-Defined Function to allow curing kinetic model. Wiresweep profiles and pressure distribution within the mold are presented. The numerical results of melt front patterns and filled volume were compared with the previous experimental results and found in good agreement.

Abstract

Sistem kendali secara otomatis di bidang ilmu pengetahuan dan teknologi belakangan ini berkembang dengan pesat. Dengan adanya kemajuan dibidang ilmu pengetahuan dan teknologi menghasilkan inovasi baru yang berkembang menuju lebih baik. Hal ini dapat dilihat jangkauan aplikasinya mulai dari rumah tangga hingga peralatan yang canggih. kemajuan ilmu teknologi dan ilmu pengetahuam tersebut telah mendorong manusia untuk berusaha mengatasi segala bentuk permasalahan yang timbul disekitarnya serta meringankan pekerjaan yang ada.  Dengan kendali jemuran otomatis ini dapat sangat membantu dalam proses menjemur pakaian, karena sistem ini menggunakan sensor cahaya dan sensor hujan untuk mendeteksi perubahan cuaca yang secara tiba-tiba. Sensor akan memberi masukan ke relay dan akan menjalankan motor DC. Relay juga akan mengendalikan perubahan arah putaran motor searah jarum jam ataupun sebaliknya seiring dengan perubahan cuaca yang terjadi.
