Experimental and Heat Transfer Analysis Using Nanofluid in Cylindrical Heat Pipe Heat Exchanger

In waste heat management systems for the utilization of heat, many new techniques are used currently, by taking into account an effective one is heat pipe heat exchanger. Three heat pipes are placed inside the heat exchanger for analyzing the heat transfer performance by using acetone and copper oxide with DI water mixture nanofluid. The influence of nanofluid for various heat input temperature conditions is studied for horizontal and vertical orientation of heat pipe. The study reveals at horizontal orientation the maximum effectiveness is obtained as 66.7% for 100 LPH and Reynolds number ranges as 1173 for similar conditions. The influence of nanofluid as heat transport fluid shows maximum heat transfer capacity for given conditions and this shows good performance in the system.
