Efficiency at maximum figure of merit of a spin half quantum heat engine in the presence of external magnetic field
K. Nilavarasi, M. Ponmurugan
We consider a finite time quantum heat engine analogous to finite time classical Carnot heat engine with a working substance of spin half particles. We study the efficiency at maxi…
Optimized efficiency at maximum figure of merit and efficient power of Power law dissipative Carnot like heat engines
K. Nilavarasi, M. Ponmurugan
In the present work, a power law dissipative Carnot like heat engine cycle of two irreversible isothermal and two irreversible adiabatic processes with finite time non-adiabatic di…
Optimized Coefficient of performance of Power law dissipative Carnot like Refrigerator
K. Nilavarasi, M. Ponmurugan
The present work investigates the generalized extreme bounds of the coefficient of performance (COP) for the power law dissipative Carnot-like refrigerator in the presence of non-a…
Novel method for determination of contact angle of highly volatile liquids
K Nilavarasi, V. Madhurima
In this paper, a novel method for the measurement of equilibrium contact angle of highly volatile binary liquids is proposed. The proposed method, which combines finite element met…
Controlling breath figure patterns on PDMS by concentration variation of ethanol-methanol binary vapors
K Nilavarasi, V Madhurima
In this paper, the self-assembly of condensed droplets on smooth and constrained surfaces under saturated vapor atmosphere of ethanol and methanol binary system is reported. Hexago…
Study of complex properties of binary system of ethanol-methanol at extreme concentrations
K Nilavarasi, Thejus R Kartha, V Madhurima
At low concentrations of methanol in ethanol-methanol binary system, the molecular interactions are seen to be uniquely complex. It is observed that the ethanol aggregates are not…
De-pinning of contact line of droplets on rough surfaces
V Madhurima, K Nilavarasi
The present study reports the formation of self-assembled droplet pattern on the PDMS polymer coated over grooved side of DVD under saturated vapours of alcohols. Comparison of the…
1D roughness driven depinning of breath figures on PDMS
K Nilavarasi, S G Ramkumar, V Madhurima
The influence of surface constraints on the self-assembly of liquid droplets is investigated. A semi-quantitative explanation for large scale pattern formation consisting of small…
