Design of shell and tube heat exchanger for ballast water treatment applications on ships based on simulation

Now, environmental issues are the mostly discussed issue and become a top priority in world. Whether it's damage or pollution. The of pollution to environment ecology region, which have an impact on living organisms, both humans, animals plants. Environmental can occur land, water, air. With various forms pollution, methods handling different. This research will focus waters as well prevention, especially marine waters. focuses designing heat exchanger by varying its types, namely shell tube exchanger. From modification model, it be known one is more effective performance. Both temperature exchange, pressure drop, flow rates, dimensions materials simulated software. Where these parameters influenced characteristics ship's power main engine. 2 model that pass-shell two result for case 1 effectiveness 92% & 93%, 93% 94% 3 95%.
