Experimental Investigation of Heat Transfer Enhancement Using Cross Inserts Having Different Pitch Rectangular Cuts
Abstract: This work presents experimental investigation of heat transfer enhancement using strip insert with cross configuration having rectangular cut. The heat transfer enhancement study in a circular copper tube of 10 mm internal diameter is carried out using three different inserts. The three inserts are of cross configuration with rectangular cuts of different pitches. The heat transfer enhancement in hydro-dynamically developed and thermally developing fluid region is studied. It is found …

Laminar Propagation of Lean-Premixed Flames in Meso-scale Tubes
Abstract: A meso-scale channel was earlier developed [1] for the propagation of laminar lean premixed flames. This paper, therefore, reports the experimental variations of flame speed with inner meso-scale tube diameters (di), equivalence ratio (φ), and mixture flow rate (Q) with methane and propane fuels using the meso-scale channel developed earlier. Based on the flame front history, flame speed (SL) and propagation speed (Ud) were computed at temperature (T) greater than …

Experimental Study on Heat Transfer Enhancement in a Mini Channel Heat Sink Using Al2O3/Water Nanofluid
Abstract: In this present work, experimental investigation of heat transfer enhancement using Al2O3/water nano fluid in a mini channel heat sink is carried out. Efforts have been undertaken to explore the forced convective heat transfer performance of Al2O3/water nanofluid having 0.1% volume fraction of Al2O3 as the coolant in a copper mini channel heat sink. The mini channel heat sink fabricated consists of 15 parallel rectangular mini-channels of length 50mm with …

Transient analysis of Earth Air Heat Exchanger using CFD for Summer Season
Abstract: Energy accumulation in the soil may be used with Earth-Air Tunnel Heat Exchanger (EATHE), which has single tube or groups of tube buried in the ground (soil). In a country like India, there exist big gap in demand and supply of electricity and compels to look for alternative. A thermal model was developed to analyze the thermal energy accumulated in soil/ground for the purpose of room heating and cooling of …
