Abstract

The main function of cooling system is to control the temperature in the engine. To know the flow in the jacket cooling system for marine diesel engine 93 KW and the couple simulation between 1D modeling and 3D modeling, the methodology used. The analysis process was performed by using 3 diffrent softwares. The methodology to analysis fluid flow is CFD (computational fluid dynamic) with steps were problem identification, literature study, design the jacket cooling system based on the cummin diesel engine 93 KW, 1D modeling of cooling system, 3D modeling fluid flow in jacket cooling system, and conclusion. The input of 3D jacket cooling simulation are mass flow, fluid temperature, wall temperature, and heat transfer. The result from this bachelor thesis is fluid flow in jacket cooling system and another parameter output such as temperature flow and velocity if fluid in the jacket cooling system. The result of the flow in jacket cooling is much turbulance in various are of jacket cooling its mean the jacket cooling have a good enfficiency of heat transfer, and the fluid temperature show the increasing temperature from inlet to outlet because of heat transfer happen in the jacket cooling between wall of jacket cooling and fluid. The engine speed will affect the cooling system, if the engine speed is increasing, the speed of flow will increase because the cylinder block need more coolant and the temperature of cylinder block will increase ================================================================================================ Fungsi utama dari sistem pendingin adalah untuk mengontrol suhu di mesin. Untuk mengetahui aliran dalam sistem pendingin jaket untuk mesin diesel laut 93 KW dan simulasi pasangan antara pemodelan 1D dan 3D, metodologi yang digunakan. Proses analisis dilakukan dengan menggunakan 3 software yang berbeda. Metodologi untuk aliran fluida analisis CFD (computational fluid dynamic) dengan langkah-langkah yang identifikasi masalah, studi literatur, merancang sistem jaket pendingin berdasarkan jintan diesel engine 93 KW, 1D pemodelan sistem pendingin, 3D aliran fluida pemodelan dalam sistem pendingin jaket , dan kesimpulan. Masukan dari 3D simulasi jaket pendingin adalah aliran massa, temperatur fluida, temperatur dinding, dan transfer panas. Hasil dari tugas akhir sarjana ini adalah aliran fluida dalam sistem pendingin jaket dan output parameter lain seperti aliran suhu dan kecepatan jika cairan dalam sistem jaket pendingin. Hasil aliran pendinginan jaket banyak turbulance dalam berbagai area pada jaket pendinginan yang berarti pendinginan jaket memiliki enfficiency baik terhadap perpindahan panas, dan suhu fluida menunjukkan suhu meningkat dari inlet ke outlet karena perpindahan panas terjadi di jaket pendinginan antara dinding pendingin jaket dan cairan. Kecepatan mesin akan mempengaruhi sistem pendingin, jika kecepatan mesin meningkat, kecepatan aliran akan meningkat karena blok silinder membutuhkan lebih banyak cairan pendingin dan suhu blok silinder akan meningkat.
