Thermofluids Lab – 3029, SAN

Crushing, Sieving and Drying

• Retsch crushing and sieving mills used.
• Average particle size: 200 µm.

Thermogravimetric Analysis (TGA)

• Performed proximate analysis using Thermo-scientific STA TA Q600
• Airflow rate: 100 ml/min

Ultimate Analysis and Heating Value

• Thermoscientific FLASH (model 2000, USA) analyzer was used to obtain elemental analysis on CHNOS basis with crucibles weighing 2-3 mg
• Parr bomb calorimeter (model 6100, USA) was used to determine heating values by pelletizing samples of 0.7-1g in an oxygen bomb

Experimental Setup

Drop Tube Reactor (DTR)

• Rectangular stainless-steel furnace.15 K-type thermocouples for temperature monitoring
• Gas sampling (Portable gas analyzer) facilitated by suction pump long stem needles
• Capable of reaching temperatures up to 1400 K
• Integrates gas delivery system, particle injection mechanism, and diagnostic instrumentation

1. Determine the lift and drag on the bluff body
2. Study the convective heat transfer
3. Visualize the flow pattern in the wake using PIV or smoke
4. Study the flow-induced vibrations of the body.
5. Study the effect of geometric arrangement of the bodies on their lift and drag

1. Seawater desalination by freezing method.
2. Waste brine management by eutectic freezing
