• An experimental technique to quantify velocity field at pore scale within micro porous media, formed by packing of micro glass spheres inside a glass micro-model, is presented. A scanning micro particle image velocimetry (µ-PIV) system is used to obtain two component two dimensional (2C2D) velocity field at two different measurement planes-one close to the glass wall and the other 100 µm below the glass surface. A combined PIV and particle tracking velocimetry (PTV) algorithm is used to quantify velocity within the micro-porous media. The probability density functions for axial and transverse velocity components at different Reynolds number are compared with available results in literature.
  The three component three dimensional (3C3D) velocity field is obtained by scanning through 100 µm inside the porous media. The pore scale velocity field obtained can provide insight to flow properties in micro-porous media and can be a powerful tool to validate existing numerical results
