in this paper, the effects of adding nanoparticles including tio2 to a fluid media for purpose of free convection heat transfer improvement were analyzed. the free convection was assumed to be in laminar flow regime and the solutions and calculations were all done by the integral method. water, as a newtonian fluid, was considered the base fluid (water) and all the thermo physical properties of...

background and objectives: thermal processing is an effective method in preventing microbial spoilage but high heat transfer in a long time process that leads to quality loss and increased energy consumption. also it is important to consider sensitive nature of food products during the thermal processing. due to the nano-fluids' unique thermo–physical properties compared with the conventio...

This paper shows the research work on heat exchanger using nano fluid. In this paper we are using compact heat exchanger as heat transferring device while Al2O3 as a nano fluid. The effect of the nano fluids on compact heat exchanger is analyzed by using ε –NTU rating numerical method on turbo-charged diesel engine of type TBD 232V-12 cross flow compact heat exchanger radiator with unmixed flui...
