Tue, 01 Dec 1998 00:00:00 GMT

Title: Asymptotic behaviour of heat and mass transfer along a vertical plate Authors: Singh, B B Abstract: The paper deals with the asymptotic behaviors of the solutions of the differential equations governing the heat and mass transfer along a vertical plate in the presence of a transverse magnetic field as the independent variable ŋ tends to infinity. The discussion being based on the asymptotic integration of second order, linear .differential equations. Here the principal solutions exhibit asymptotic nature as ŋ→∞ where as the independent solutions do not. Page(s): 488-489

A new technique for magnetite particle size reduction-Relevance to magnetic fluid preparation

Tue, 01 Dec 1998 00:00:00 GMT

Title: A new technique for magnetite particle size reduction-Relevance to magnetic fluid preparation Authors: Pant, R P; Rao, N N; Mehta, R V; Suri, D K Abstract: Commercial magnetite powder was ballmilled at liquid nitrogen temperature. Particles were reduced to colloidal size after about 72 h of grinding. The method is found to be suitable for preparation of non-aqueous based magnetic fluid. Page(s): 485-487

Synthesis and characterization of ionic ferrofluid and its composite films

Tue, 01 Dec 1998 00:00:00 GMT

Title: Synthesis and characterization of ionic ferrofluid and its composite films Authors: Pant, R P; Mehta, R V; Suri, D K Abstract: An aqueous based magnetic fluid having particle size ranging from 2 to 8 nm and the saturation magnetization of 80 G was prepared. This has been used to prepare composite films under the influence of With and Without magnetic field in the polymer matrix. The changes in physical properties of these ferrofluid polymer composite films due to the freezing of domains under the different experimental conditions were studied by TEM and XRD techniques.

Applications of magnetic fluid

Tue, 01 Dec 1998 00:00:00 GMT

Title: Applications of magnetic fluid Authors: Bhatt, R K Abstract: In last few years numbers of new applications of magnetic fluid have been emerged i.e. inertial dampers, rotating shaft seals, loud speakers, gauges and sensors. Such applications of magnetic fluid rely on their basic properties such as the ability to flow and conduct magnetic flux, levitation of magnetic or nonmagnetic objects etc. This paper shows two different applications of magnetic fluid-pressure sensor based on magnetic fluid and magnetic fluid as a coolant.
