Abstract

Setiap engine builder telah memheri hatasan maksimum untuk back pressure yang diijinkan, oleh sehah itu dalam merancang pipa gas huang hams henar - henar diperhitungkan mengenai terjadinya back pressure yang herlehih. Back pressure pada pipa gas huang dipengaruhi oleh panjang pipa, fitting pipa dan peletakan pipa. Pada kapal patroli cepat milik TNI-AL FPB 57 pipa gas huangnya herada dihawah garis air. Hal ini akan mempengaruhi back pressure yang terjadi karen·a gas huang yang keluar akan terhalang oleh air dan menimhulkan tahanan lehih hesar. Dalam penelitian ini dilakukan perhitungan secara matematis dan juga pemodelan dengan so.ftwere CFD dan heherapa variasi kecepatan kapal dan kedalaman pipa gas huang. Hasilnya back pressure yang terjadi tidak melebihi batas back pressure engine yang ditentukan engine builder.
=======================================================================================================================================
Every engine builder has given the maximum limit for each engine back pressure, thus, the exhaust gas pipe design must be arranged so that the back pressure doesn't exceed the maximum limit. The back pressure in an exhaust gas pipe is affected by the length of the pipe, fittings, and piping placement. Fast patrol boat of TNI-AL (FPB 57), has the exhaust gas pipe under the water line. This will affect the back pressure of the engine, since the water will block the exhaust gas pipe and results in increase of the back pressure. In this final project, will be performed the mathematic calculation and simulated by CFD Software, with several variation of ship's speed, and the depth of the exhaust gas pipe. The result is the back pressure occurred in exhaust gas pipe, doesn 't exceed the maximum limit of the engine back pressure.
