Thermal Contact Resistance of Wavy Surfaces (RESEARCH NOTE)
In this paper, the method of determining thermal contact resistance of wavy surfaces is discussed exactly. For determining the thermal contact resistance of real contacts, a new method has been presented. In this method, assuming a regular sinusoidal surface profile, the real contact area in terms of applied forces has been determined. Then thermal contact resistance has been calculated. Testin...
متن کاملThermal Contact Resistance of Nonconforming Rough Surfaces, Part 1: Contact Mechanics Model
A new analytical model for spherical rough contacts, in the form of a set of relationships, is developed and solved numerically. It is shown that the maximum contact pressure is the parameter that specifies the contact pressure distribution. Simple correlations for calculating the maximum contact pressure and the radius of the macrocontact area as functions of the nondimensional parameters are ...
متن کاملThermal Contact Resistance of Nonconforming Rough Surfaces, Part 2: Thermal Model
A new analytical model is developed for thermal contact resistance (TCR) of nonconforming rough surfaces. TCR is considered as the superposition of macroand microthermal resistances. The effects of roughness, load, and radius of curvature on TCR are investigated. It is shown that there is a value of surface roughness that minimizes the TCR for a fixed load and geometry. Simple correlations for ...
متن کاملAIAA 2003-4198 Thermal Contact Resistance of Non- Conforming Rough Surfaces, Part 2: Thermal Model
Thermal contact resistance (TCR) of non-conforming rough surfaces is studied and a new analytical model is developed. TCR is considered as the superposition of macro and micro components accounting for the effects of surface curvature and roughness, respectively. The effects of roughness, load and radius of curvature on TCR are investigated. It is shown that there is a value of surface roughnes...
متن کاملContact mechanics for randomly rough surfaces
When two solids are squeezed together they will in general not make atomic contact everywhere within the nominal (or apparent) contact area. This fact has huge practical implications and must be considered in many technological applications. In this paper I briefly review the basic theories of contact mechanics. I consider in detail a recently developed contact mechanics theory. I derive bounda...
