DEVELOPMENT OF A CAR FIRE ÎN A ROAD TUNNEL
The article presents the work of the authors concerning the burning
test in a semi closed space involving stationary car model. One scenario
considering a fire at one car caught in a road tunnel. Taking into consideration
fully developed fire, the temperature evolution, the time for temperature
increase and smoke spread and their meaning in case of a real event. The
results give us an image about user chances of escape from an event like this,
using both physical and numerical scalarization methods.
Keywords: road tunnel fire, car mode, smoke spread, scalarization
Cuvinte cheie: incendiu tunel rutier, model de mașină, răspândirea de

PROPER IMPLEMENTATION OF CAR FIRES HRR IN COMPUTER SIMULATION PURPOSE
The article presents the work of the authors concerning establishing the HRR (heat release rate) for modern cars considering the new materials used to build them. In order to do this, large scale test were studied involving small and middle size cars, in purpose to measure the burning time and determine HRR (heat release rate) using the oxygen calorimetric method. The results obtained are compared with some others similar results and become very important for knowledge and for establishing protection measures especially for close and semi-closed spaces crossed by cars.
Keywords: HRR, real scale test, simulation, oxygen calorimetric method

MEASURES TO IMPROVE THE LEVEL OF
ENVIRONMENTAL POLLUTION IN CITIES TUNNELS
Nowadays, many tunnels are built below underground water level. This means that, in case of a fire or oil spill there is a risk of environmental contamination of ground water supplies or sensitive recipients.
This paper purpose is to analyse the environmental consequences of a tunnel fire or an oil spill inside the tunnel.
There are presented from the beginning study of existing technologies.
Also, the paper focus on the new technologies for on-site collection and treatment of water, not to minimize the importance of in-situ treatments both prior to and after an incident, those being sustained by new mobile technologies for effective treatment.
Keywords: oil spill, water treatment, soil treatment, contamination transport

COMPUTATIONAL FIRE SIMULATION TO A CAR IN A SEMICLOSED SPACE
The article presents the work of the authors concerning the 3D fire simulation at a semi closed space involving one stationary car. A simulation using Pyrosim software is based on the physical model in which one electrical fault accident involving a car appear. The accident, consisting in a fire event at one stationary car, is modelled at 1.5 m from height. Considering an electrical fault followed by a fire, we obtained temperature fields and smoke spread depending on time in this tunnel. These information allow us to realize an appropriate impact on the event in aim of minimizing the time for a promptly intervention.
Keywords: road tunnel fire, heat release rate, Pyrosim software

23-28 CONSIDERENTE ASUPRA STADIULUI ACTUAL AL IMPLEMENTĂRII MĂSURILOR DE SECURITATE ALE TUNELURILOR RUTIERE DIN ROMÂNIA

CONSIDERATIONS ON THE CURRENT STATUS OF
ROMANIAN ROAD TUNNELS SECURITY MEASURES
IMPLEMENTATION
In our country only 9 road tunnels are built, totaling a length of only
1.6 km and an average age greather than 30 years. The longest tunnel is 884
long, located on Transfagarasan road and is unenlightened and airflow. Given
the age and length of tunnels, fire safety measures are virtualle non-existent in
our country road tunnels. It is generally noted the need for fire safety minimum
measures and new road tunnels building.
