Experimental And Numerical Modeling

The carbon surface saturation process of the steel plates during the catalytic gas carburization was under consideration. The rate of the carburization was determined, as well as the hardness of the diffusion layer, after quenching. A mathematical model based on experimental and numerical modeling data had been obtained. The carbon concentration profile of the surface layer was estimated depending on the carburization process parameters. A simplified simulation technique of the steel carburization was proposed.

Atlikti eksperimentiniai tyrimai siekiant nustatyti į aplinkos ora išsiskiriančių dujų kiekius degant įvairių rūšių medienos kurui – malkoms, granulėms, briketams ir pjuvenoms. Dujų analizatoriumi Testo-350 išmatuotos degimo metu į aplinkos ora išsiskiriančių dujų – anglies monoksido (CO), azoto oksidu (NOx) koncentracijos dumuose, deguonies (O2) kiekis, taip pat dūmų temperatūra koncentracijų matavimo vietoje. Remiantis atliktais eksperimentiniais tyrimais pagal PHOENICS programa sumodeliuota anglies monoksido ir azoto oksidu koncentracijos sklaida atmosferoje iš taršos šaltinio (kamino aukštis 13 m), esant tam tikrai eksperimento metu nustatytai koncentracijai. Gauti rezultatai pateikti horizontaliojoje ir vertikaliojoje plokštumose. Atlikti teršalų emisijų pažemio koncentracijos skaičiavimai pagal banguotaja ir kūgiškaja atmosferos stabilumo formas. Gauso metodu apskaičiuoti tiriamu teršalu pažemio koncentracijų maksimumai. Modeliavimo duomenys palyginti su skaičiavimu rezultatais. Abstract An experimental research has been performed during which different kinds of wood – fire wood, granules, briquettes and sawdust – were used for defining the gas quantities emitted in the atmosphere. During the test, when applying the analyser Test-350, it was measured the concentrations of carbon monoxide (CO), nitrogen oxides (NOx) in the fumes, the quantity of oxygen (O2) and fume temperature in the measuring place. According to the performed experimental investigations (by using PHOENICS programme), the diffusion of carbon monoxide and nitrogen oxides concentration in the atmosfere from the pollution source has been modeled (the hight of the chimney was 13 m).The results are presented in horizontal and vertical planes. The lower level concentration calculating was performed by applying the wavy and conical forms of at- mospheric stability. The maxima of investigated concentrations have been found by Gauss method. The modeling data are compared with the results obtained by calculations. Резюме Проведены экспериментальные исследования, во время которых прибором Test-350 измерялись концентрации эмиссий CO и NOx, выделяемых при сжигании древесного топлива. По данным эксперимента с помощью программы PHOENICS построена модель рассеяния концентраций эмиссий CO и NOx в атмосфере из источникаэмиссии при высоте дымовой трубы в 13 м. Полученные результаты представлены в горизонтальном и вертикальном сечениях. Вычислены концентрации газовых эмиссий над поверхностью земли на разном расстоянии отместа выброса и установлены их минимумы. При вычислении максимальных надземных концентраций изучаемых эмиссий использован метод Гаусса. Проведен сравнительный анализ результатов вычислений и моделирования.

Up Scaling

An innovative sand cementation method of bio-mineral carbonate formation in sand spacing through urea hydrolysis inspired by microbial urease was introduced in the present investigation. A sand column prepared for experimental data and a set of engineering equations for 1-D numerical modeling data of the sand cementation process were adopted. Important characteristic of CaCO3 weight vertically along the sand column and the urea concentration variation under the effect of microbial urease was investigated based on the experiment and the modeling. Future study was suggested to focus on the models parameters modification in order to construct an applicable model for industrial up-scaling application in sand or soil strengthening.
