It is very important to accurately predict the fire-induced air velocity, temperature, and smoke concentrations in tunnel fires to design efficient fire protection systems. In this study a scaled model of a tunnel was constructed based on Froude number scaling and wood sticks with different configurations which were burned in a controlled environment. Model vehicles having a square base were built according to the wood crib theory. The impact of varying longitudinal ventilation velocity and the cross-sectional area of the burning substances on the heat release rate and temperature distribution in the tunnel were measured.

An experimental study on the burning rates of interacting fires in tunnels SHAFEE, SINA; Yozgatlıgil, Ahmet (2018-03-01) Multiple fires may occur in close proximity in process industries, power generation and fuel storage facilities and confinement conditions such as tunnels, which can lead to a considerable alteration in fire characteristics and safety design. The topic is of significant importance to the fire safety research because there is little work in the literature that investigates the case of interacting fires, which have a destructive potential. In this work, we study the effects of an adjacent fire source on the b...
An Experimental and numerical study on the combustion characteristics of pool fires in tunnels Shafee, Sina; Yozgatlıgil, Ahmet; Department of Mechanical Engineering (2017) This work presents the results of experimental and numerical analysis on tunnel fires in an attempt to improve existing knowledge on the fire dynamics and related safety measures in various tunnel fire scenarios. Results are grouped into four parts in which the effects of tunnel wall coating, inclination, tunnel obstruction and existence of secondary fire source in close vicinity were investigated on tunnel fire characteristics. A 1/13 longitudinally ventilated scaled tunnel model constructed based on Froud...
An analysis of tunnel fire characteristics under the effects of vehicular blockage and tunnel inclination SHAFEE, SINA; Yozgatlıgil, Ahmet (Elsevier BV, 2018-09-01) It is known that the blockage and inclination conditions of tunnels are among the important factors affecting fire safety considerations, as these factors could change the characteristics of possible fire incidents as well as smoke movement in tunnels. In the present work, we analyze the variations of the tunnel fire burning rate, heat release rate and smoke backlayering as being functions of these two factors. Ethanol pools were used as fire sources in a reduced scale tunnel model with longitudinal ventila...
Experimental Investigation on the Mass Loss Rates of Thin-Layered n-Heptane Pool Fires in Longitudinally Ventilated Reduced Scale Tunnel Shafee, Sina; Yamali, Uluc; Yozgatlıgil, Ahmet (2017-01-01) Thin-layered n-heptane pool fires are burned with varied pool depths under longitudinal ventilation velocities ranging between 0.5-2.5 m/s in a reduced scale tunnel model. The combined effects of ventilation, pool size, and depth are investigated on the heat release rate, temperature distribution, and mass loss rate of fire. The gas temperature distribution and heat release rate results indicate that the critical ventilation velocity is achieved around 1 m/s in the scaled model, corresponding to 3.6 m/s in ...
An Experimental and numerical investigation of warpage behavior of silicon substrates at cryogenic temperatures Baloğlu, Eyüp Can; Okutucu Özyurt, Hanife Tuba; Dursunkaya, Zafer; Department of Mechanical Engineering (2016) Surface deformations and thermal stress behavior of microelectronic devices that operate at cryogenic temperatures (less than 120 K) and under vacuum conditions are important phenomena that aff ect the reliability requirements of such components. Excessive deformation and thermal stress on these devices may result in interconnect failure, performance degradation or other direct mechanical failure of one or more components. To obtain reliable products, surface deformations, named as warpage most widely, and ...
