Table 2 Controlled and variable parameters
From: Application of silver nanofluid containing oleic acid surfactant in a thermosyphon economizer
The tubes were arranged in a staggered | |
|---|---|
Operating temperature of 60,70 and 80°C | |
The controlled parameters | Silver nanofluid concentration of 0.5 w/v% |
Volumetric flow rate was 5 l/min in evaporator section | |
Cool water flow was 25°C in condenser section | |
Working fluid = pure water, silver nanofluid concentration of 0.5 w/v% and silver nanofluid concentration of 0.5 w/v% mixed oleic acid surfactant | |
The variable parameters | Concentration of oleic acid surfactant were 0.5, 1, 1.5 w/v% |
Volumetric flow rate were 1, 2, 5 l/min in condenser section | |
Filling ratio = 30, 50, and 80% (by total length of evaporator) |
