Abstract:

The main objective of this project is the investigation of hydrogen influence on gas-phase combustion of hydrocarbons in air, in deflagration regime, by experimental and numerical methods. Under the project, relevant initiation parameters (the quenching distance and the minimum ignition energy) and propagation parameters (normal burning velocity and propagation speed) will be examined, in correlation with the initial composition and pressure of flammable mixtures and with characteristic flame properties (adiabatic flame temperature, total concentration of active radical species).

The study will be realized with LPG (Liquefied Petroleum Gas)-air mixtures with added H2, at various initial LPG concentrations within its flammability limits, hydrogen fractions (5-30 vol%) and initial pressures, within 0.5 and 2.0 bar, at ambient initial temperature. LPG has the typical composition of Romanian blends.

The estimated scientific results delivered by the project consist in the full characterization of LPG-air-H2 mixtures from point of view of flammability parameters, in order to obtain safety operating characteristics for storage, transport and manipulation of such mixtures and to develop increased energetic efficiency with low pollutant emissions.

Abstract:

In the field of curing different maladies the current medicine make special efforts for the control of factors that favor their appearance together with pathogen agent surveillance. The development of modern medicine is strongly influenced by technology and in this view together with the development of tissue engineering it was tried the creation of a replacement for human bony tissue. In the preset project the research efforts from the forth component projects are implied in:1- antimicrobian nanomaterials; 2- biomaterials for tissue regeneration and for diagnosis, prevention and treatment of osteoporosis; 3- intelligent nanocomposites for diagnosis and treatment bony cancer; 4- nanostructured probes dedicated to diagnosis. The research concerning the obtaining of new intelligent bioceramics with antiseptic properties dedicated to bony tissue regeneration together with their physical-chemical characterization implies the elaboration of protocols for obtaining, analysis and prophylaxis at laboratory animals tests level. Biomaterials application in the field of tissue regeneration for osteoporosis case will bring experimental data related to structural and morphological characterization of nanomaterials together with information regarding biocompatibility and cytotoxicity. These data that will lead to composites optimization as a function of histological character common to laboratory animals. The study of intelligent nanocomposites will open a direction related to their action in bony cancer case. The development of photoluminescent biocompatible ceramic nanomaterials is dedicated to bony screening and further more will their functionalization with anti-inflammatory materials in order to evaluate their in vivo action and their possible using as biological probes. The statistics for the osteoporosis appearance in different population decades indicate their maximum in the (41-60) age limit, and in this view, the studies presented in this project are of general import

Abstract:

The main objective of this project is the experimental investigation of closed-vessel explosive combustion of fuel-air mixtures, in deflagration regime, in elongated cylindrical vessels (length/diameter > 3) in order to reveal the heat losses during flame propagation and to evaluate their impact on the flammability parameters. In these vessels, both central and side ignitions will be performed.

The study will be realized with ethylene-air mixtures at various initial concentrations and various initial pressures, at ambient initial temperature. The objectives of the project are: (1) The experimental determination of the maximum explosion pressures and explosion times for ethylene-air mixtures at various p0 in elongated cylindrical vessels with various L/D ratios; (2)The calculation of adiabatic explosion pressures for fuel-air mixtures within the flammability range at ambient p0, using available computer packages; (3) The calculation of the maximum rates of pressure rise for fuel-air mixtures with various equivalence ratios at various p0 in elongated cylindrical vessels; (4) The experimental determination of the propagation velocity for deflagrations of ethylene-air mixtures at various initial pressures in elongated cylindrical vessels. The knowledge of characteristic parameters of these processes allows the assessment of explosion risks for flammable mixtures in various conditions and the design of equipment and industrial plants where flammable mixtures might be formed.
