Porous titanium fibre materials with different structural parameters were prepared by vacu-um sintering method.The thickness, porosity and wire diameter of prepared materials were investigated to understand the effects of structural parameters on pool heat transmission performance of titanium fibre porous material.As a result, better heat transfer performance is obtained when overheating is less than 10℃.In addition, when the wire diameter is smal-ler, the heat transfer is better.However, when superheating is above 10℃, heat transfer performance can be improved by increasing the wire diameter.Moreover, thickness influ-ences the superficial area of the prepared material and affects the thermal resistance when bubbles move inside the material; superficial area and thermal resistance are the two key factors that jointly impact the heat transfer in relation to the thickness of the materials.Ex-perimental results also show that the materials of 3 mm in thickness exhibit the best per-formance for heat transmission.Furthermore, changes in porosity affect the nucleation site density and the resistance to bubble detachment; however, the nucleation site density and the resistance to bubble detachment conflict with each other.In summary, the titanium fi-bre porous material with a 50% porosity exhibits suitable heat transfer performance.
