The vortex tube is a device, which emanates hot and cold air streams simultaneously at its two ends from a source of pressurized air: warmer, gas leaves near the periphery at one end as a free vortex and colder, gas leaves via an orifice at the opposite end as a forced vortex. The forced vortex strikes back again by design modifications, result in the formation of one more forced vortex flow. Thus, the modified vortex tube is named as dual forced flow vortex tube (DFFVT). Experimental study is carried on temperature separation of DFFVT for varying pressures, mass flow rates and optimum cold fractions at two ends for efficient temperature drop is revealed. The modified vortex tube yields effectual temperature drop through one end at a lower cold fraction meanwhile providing effective cooling at the other end with higher cold fraction and vice versa.
