Project summary

The project deals with the development of over-all mathematical model of forest fire initiation and dynamics, experimental study of forest fires characteristics and, as a result, development of new efficient methods of fighting them.

The goal of the project is:


- Formulation and numerical solution of new forest fire theory problems in order to study laws of initiation and dynamics of low and crown forest fires in two-dimensional approximation, in order to study shock-wave interaction with a forest fire front;
- Obtaining, by means of experiments, more precise knowledge of a number of forests fires qualities;
- Developing databases on forest fires: thermal and physical properties of gases, multiphase environment structure characteristics, heat exchange coefficients, data on timber combustible materials' drying, pyrolysis, and burning kinetics, experimental techniques review, experimental study results on forest fires, etc;
- Developing timber combustible material (TCM) ignition models and formulating new problems of low and crown forest fires initiation and dynamics;
- Developing a package of two-dimensional mathematical programs for predicting forest fire initiation and dynamics;
- Experimental study of initiation and spread of low forest fires and comparison of test results with theoretical predictions;
- Experimental study of damaging factors from forest fires and calculation of minimum permissible distances;
- Experimental study of influence of various forces on initiation and spread of low and crown fires;
- Choice of promising trends of fighting forest fires;
- Development of proposals on new more efficient methods and ways of fighting forest fires.

The scientific significance of the project is that the study under this project will allow to obtain for the first time considerably more complete patter of forest fire dynamics, to obtain more precise knowledge of marginal conditions of forest fire initiation and spreading, to choose promising trends in extinguishing methods, to suggest development of new, more efficient ways of fighting forest fires.

Commercial significance: the study will permit to develop calculation techniques for initiation and spread of forest fires. Promising trends will be proposed on extinguishing methods and new, more efficient methods of fighting forest fires will be put forward.

The main results of the work are to be of applied nature. In reports and articles mathematical modeling methods will be presented of initiation and dynamics of forest fires and effects of various physical factors upon these phenomena will be studied. In particular, mathematical modeling will be made of initiation and dynamics of crown and lower forest fires. Blast's interaction with crown and lower fire fronts will be investigated; effects of anti-fire gaps and barriers on forest fire spreading will be studied.

Basing on this research, promising trends will be chosen and new methods of fighting with forest fires practical recommendations on preventing and extinguishing forest fires of different intensity will be given.

Results of this research can be useful for mathematical modeling not only of forest fires but also of fires on other objects.

The main results appearing within the project work are to be presented in reports and submitted to periodicals.

Potential role of foreign collaborators: the foreign collaborators will participate in discussing the results of research, that will take place during international conferences on «Forest fires: origin, propagation and extinguishing» and workshops to be organized one time per annum. Due to possible collaborators' request it may be performed the mathematical experiments on forecasting the forest fire propagation in their states as the collaborators will give necessary initial data.
